Full transcript

1. 0:01hello Priya how are you yeah I'm good
2. 0:04how are you I'm fine thank you so much
3. 0:06for
4. 0:07joining uh so how much experience you
5. 0:10have yeah so I overall have two plus of
6. 0:13years experience in service no developer
7. 0:16and also in
8. 0:17it okay great so can you please provide
9. 0:19your brief
10. 0:21introduction yeah sure so um myself
11. 0:24briya I completed my graduation in
12. 0:26electronics and communication
13. 0:27Engineering in 2021 and later I have
14. 0:30started my it career and it's been like
15. 0:32overall 2.5 years of experience I have
16. 0:35as a service node developer I'm working
17. 0:37and uh relevant experience is also 2.5
18. 0:41years and then I have uh started working
19. 0:44in one of the uh mnc's and I have no
20. 0:47good knowledge on majorly all itm
21. 0:50related modules and have experienced in
22. 0:53creating configuring
23. 0:54workflows uh service cataloges business
24. 0:57tool client scripts and all itm majorly
25. 0:59it assim related
26. 1:01yeah okay thank you so as you said you
27. 1:05have experience in itm so can you tell
28. 1:07me what is
29. 1:09itm uh yeah itm is like uh it uh it
30. 1:13service management it deals is merly uh
31. 1:18endend delivery of IT services to the
32. 1:20customers or
33. 1:22clients okay so from like from the
34. 1:25starting to end process like designing
35. 1:27and then creating and then supporting it
36. 1:29and in it it deals with all
37. 1:33those okay so can you give any
38. 1:37example uh example suppose if you uh say
39. 1:42if you if any company having their
40. 1:44specific products that they were selling
41. 1:46uh into the market then with this uh itm
42. 1:50help we can create some uh Pages like
43. 1:52service cataloges where they can submit
44. 1:55their orders same we have like Amazon
45. 1:57where we can give the orders and then in
46. 1:59the the background that people can work
47. 2:01on that and provide that delivery to the
48. 2:03client or to the
49. 2:05customer okay so this delivery is known
50. 2:08as delivery of IT services okay so do
51. 2:12you know about change
52. 2:14management uh yeah I'm not majorly
53. 2:18worked on it but I know a little bit
54. 2:20about it okay can you tell me what is
55. 2:22change management and what are the types
56. 2:24you have heard
57. 2:26of type of changes okay
58. 2:31okay uh so whenever any problem is
59. 2:34created and uh that resolution comes uh
60. 2:37when we when we have a problem there
61. 2:38will be some uh root cause analysis that
62. 2:41we did we do for the problem and then we
63. 2:43come across any updates or anything that
64. 2:45need to be changed then we will raise
65. 2:47that change request that what need to be
66. 2:49changed for that particular uh
67. 2:54problem
68. 2:57okay yeah yeah any example
69. 3:00uh like uh do you know the types of
70. 3:03changes uh types of changes I'm not able
71. 3:08to recall at the moment okay no problem
72. 3:11uh have you created any change till now
73. 3:14oh no okay okay fair enough no problem
74. 3:18uh so I see you have worked on SLS right
75. 3:21yeah can you tell me what are
76. 3:23retroactive
77. 3:25slas what is the meaning of retroactive
78. 3:28SLA
79. 3:30re act
80. 3:36uh so uh what I understood I I will
81. 3:40explain suppose once we create that SLA
82. 3:42we have some specific time like when
83. 3:45that uh should when that in task SL SLA
84. 3:49should be
85. 3:50completed
86. 3:52so this retroactive uh maybe like a
87. 3:56timing where we will calculate that uh
88. 3:59how much timeing left like date in the
89. 4:01past and how much time it's still now
90. 4:03I'm not sure I'm just assuming that okay
91. 4:07so you know this is not retroactive SLA
92. 4:09it means retroactive
93. 4:12means doing calculations from the past
94. 4:15date as well okay so suppose you have
95. 4:17created SLA today but the process is on
96. 4:19from last five months so or or let's say
97. 4:23incident is on from the last five months
98. 4:25so it will do the calculations from past
99. 4:28date not today okay okay so this is
100. 4:30known as
101. 4:31retroactive okay so have you written any
102. 4:34server side code yeah I did okay so how
103. 4:38many ways you write means what are what
104. 4:41all are the utilities in service now
105. 4:43where you can write server side
106. 4:45codes yeah so we will write this server
107. 4:48as grop in business rules UI actions and
108. 4:51in scripting CL we will uh write this
109. 4:54okay any
110. 4:57other uh
111. 5:00[Music]
112. 5:03uh I I remember only these for now okay
113. 5:07okay no problem so this UI action is it
114. 5:11server side or client side we can use
115. 5:14that both in u u action both in server
116. 5:17side and client side but if we want to
117. 5:19use that uh in client side there will be
118. 5:22we have uh client we will have this
119. 5:24client check box we have to uh tick that
120. 5:26to make that client
121. 5:28callable okay okay great okay let's move
122. 5:32to the next question uh have you used G
123. 5:35scratch Pad
124. 5:37variable yeah we use that in uh display
125. 5:40business to to call
126. 5:43uh uh to call to client side server side
127. 5:46data to client side okay so to retrieve
128. 5:49data yeah okay so what are display
129. 5:53business
130. 5:55rules uh dis business rule are like when
131. 5:58we want to uh it will execute like uh
132. 6:02when before the form is presented to the
133. 6:04user and data is saved into the database
134. 6:07so if you want to uh give or you want to
135. 6:09display any information to the client
136. 6:12even before uh us submit any information
137. 6:15we will use this display business R okay
138. 6:18any scenario you have in mind where we
139. 6:20can use this type of
140. 6:24thing uh just a minute I think take a
141. 6:28Time
142. 6:39okay so uh suppose when any user or uh
143. 6:46if any user belongs to one suppose he
144. 6:48belongs to some Australia company and in
145. 6:50the form uh he only the form need to
146. 6:53only display based upon his comp uh his
147. 6:57country specific data then we will use
148. 6:59display business
149. 7:01tool okay okay let's move to the next
150. 7:05question so have you used flow
151. 7:08designer yeah uh I didn't work but uh
152. 7:11yeah I know I got good knowledge on FL
153. 7:13designer okay so uh can you tell me the
154. 7:16difference between the workflow which we
155. 7:18have traditionally right from bong and
156. 7:21this flow designer what difference you
157. 7:25feel uh actually the latest I mean the
158. 7:28advanced verion of workflow uh is the
159. 7:31flow designer suppose in flow designer
160. 7:34we can have this uh we have this
161. 7:36platform op where we have parall create
162. 7:38multiple
163. 7:40subflows okay and uh instead of uh
164. 7:45writing any scripts we can easily uh use
165. 7:48this flow
166. 7:50designer
167. 7:53okay um and we uh suppose we will have
168. 7:57this data pills all those which we which
169. 8:00makes the process simply simpler and
170. 8:03easy to understand and take less time to
171. 8:06code in FL designer than workflow and
172. 8:09there is some reusable action suppose in
173. 8:11one FL designer if you used any action
174. 8:14the same thing we can use in uh another
175. 8:16flow designer also okay okay great good
176. 8:21example okay so uh you worked on Agile
177. 8:25development so right yeah
178. 8:29so what is this agile thing how we why
179. 8:33we are using it and what is the basic of
180. 8:37agile okay so aile development is like a
181. 8:40uh flexible approach suppose we have
182. 8:42some uh we got got some requirement we
183. 8:45need to complete in so on so date before
184. 8:47the headline then we make a proper
185. 8:49planning like uh it's like a management
186. 8:53like how many uh in the way how we have
187. 8:55to deliver
188. 8:58that okay so basically it is a kind of
189. 9:02software development
190. 9:06cycle yeah I think
191. 9:08so okay so I see you have hands-on
192. 9:12experience in driving upgrades
193. 9:15right yeah so in
194. 9:19upgrade what was your
195. 9:23role uh first of all tell me uh which
196. 9:26which release of upgrade you were in
197. 9:32involved uh I don't play majorly but uh
198. 9:35while uh people are upgrading I just uh
199. 9:40I will also be uh I'm invited to that uh
200. 9:43calls and I will also just have I still
201. 9:46have to know that I'm not sure exactly
202. 9:49okay so so what you did basically just
203. 9:52wanted to check in all the upgrade
204. 9:57process uh okay you did testing or
205. 10:01what uh no once we upgrade from uh
206. 10:05suppose if you upgrade to another uh
207. 10:07release then we will make in the back
208. 10:09end we will see that if we have same
209. 10:12number of updates that there previously
210. 10:15before and the updates we have done
211. 10:17we'll just compare before and after and
212. 10:21yeah okay and if it's anything missing
213. 10:24we will load that uh update set to the
214. 10:27new release okay
215. 10:29so I say you have also experience on
216. 10:32fixed scripts right yeah you know what
217. 10:35is the fixed script can you tell me what
218. 10:37is the use of fix script and where we
219. 10:39are using
220. 10:41it okay so uh if we have a large data
221. 10:45that we need to uh we need to update
222. 10:48then we will use this uh fix
223. 10:50script
224. 10:52okay so uh when we trigger this fix fix
225. 10:58script
226. 11:06okay no problem let's move to the next
227. 11:08one uh um do you know what are import
228. 11:13sets huh I know yeah please tell
229. 11:17me yeah import set like uh suppose in in
230. 11:22service not to uh navigate from one
231. 11:23instant we will use uh update set and
232. 11:26data sources so import set is like a uh
233. 11:29we will import the data firstly to the
234. 11:31import set and then we from import set
235. 11:33we will transfer the data to Transformer
236. 11:35to the Target
237. 11:37table okay but this is used for moving
238. 11:40of data from outside systems yeah it is
239. 11:43like a staging
240. 11:44table okay okay fair enough so I have
241. 11:48one you
242. 11:49know some one question where you have to
243. 11:53build some logic okay just just listen
244. 11:56carefully okay so I have a spread sheet
245. 12:00which is present on a server location
246. 12:02okay so there is a server and someone is
247. 12:06adding a spreadsheet with the same name
248. 12:08on every week there what I want I want
249. 12:12to move that spreadsheet or you can say
250. 12:15data from that spreadsheet of that Excel
251. 12:18into one of my custom table every day
252. 12:21not every day every
253. 12:23week okay so there is a server we have a
254. 12:25file on that and that file I want to be
255. 12:28loaded service now tables or one of the
256. 12:31table every week okay so how should I
257. 12:34approach
258. 12:36it um we can create a schedule job with
259. 12:39by mentioning like uh time as one we and
260. 12:42what need to be
261. 12:44done okay that schedule job is okay but
262. 12:47what we will do in that schedule
263. 12:57job
264. 13:01I'm not able to recall it I didn't work
265. 13:05much on schedule job I just lent on my
266. 13:08own
267. 13:09okay no issues uh have you worked on
268. 13:14ATF uh yeah uh manual testing yeah we
269. 13:17are currently uh did for one of the
270. 13:20project and atfs yeah I have created a
271. 13:22few ATS for cataloges and testing the
272. 13:26workflows Okay so can you tell me how to
273. 13:30configure an ATF what are the
274. 13:33steps okay so we will have the separate
275. 13:36module in our PDI only to create ATF and
276. 13:40uh there we will have this or few
277. 13:43already existed templates if we want we
278. 13:46can use get once we uh template we can
279. 13:48use them suppose if you are creating any
280. 13:50incident then there are already
281. 13:52pre-build templates for the incident we
282. 13:54can make use of them or you can create
283. 13:56then some custom steps
284. 13:59uh Customs test steps for each uh test
285. 14:02suit and then according to the condition
286. 14:05you can build
287. 14:07those okay can we schedule
288. 14:11atfs uh yes I uh yes I think yeah we can
289. 14:16schedule an ATF okay okay uh fair so
290. 14:22have you created any
291. 14:25ACL uh
292. 14:27yeah so tell me what you did in that ACL
293. 14:33creation what was your
294. 14:36task okay so uh ACL suppose if you want
295. 14:41to make any um ACL is generally not to
296. 14:44restrict any user like uh which data he
297. 14:47has to modify and which data he has
298. 14:50to uh so by using this ASL we have uh
299. 14:55suppose we can give condition suppose if
300. 14:58you in instant table we have one record
301. 15:01where there will be one field if you
302. 15:02want that field to be visible only to
303. 15:05that particular role person then we can
304. 15:08create ACL like by giving condition like
305. 15:11this can be accessible we have this two
306. 15:14uh types in like lower level and field
307. 15:16level ACL in field level ACL we can use
308. 15:18this field level AC and create give
309. 15:21conditions like this specific field
310. 15:22should be uh used by this person only
311. 15:25and we can do that accordingly okay okay
312. 15:28so which level of ACL execute
313. 15:32first field level or row level or you
314. 15:35can say table level table level AC okay
315. 15:39and then it will go to field
316. 15:42level okay okay great so have you worked
317. 15:45on any Integrations till
318. 15:47now uh Integrations I didn't work but uh
319. 15:51I learned
320. 15:52Integrations I sorry sorry but I know I
321. 15:56I have good knowledge on them okay give
322. 15:58me one example whatever you feel
323. 16:01good okay suppose if you are integrating
324. 16:04with uh with service now with Postman
325. 16:08then we need first the endpoint like the
326. 16:10URL of that Postman and uh we'll get
327. 16:14that endpoint URL of that Postman and in
328. 16:17the service now we will open this rest
329. 16:19uh API Explorer and we will provide that
330. 16:22Postman end URL into this uh service now
331. 16:25and uh if you need any authorization we
332. 16:28will give those credentials and then we
333. 16:30will integrate
334. 16:32according okay so what basically we are
335. 16:34doing you you do in this integration I
336. 16:37you told me the steps but but what is
337. 16:39happening why integrate with something
338. 16:43else to exchange information suppose if
339. 16:46we want any information from third party
340. 16:48we'll use this integration uh to build
341. 16:50like a connection between two
342. 16:52applications okay
343. 16:55great
344. 16:57Okay so uh what is the background
345. 17:01script uh back background script in
346. 17:04service now used to uh suppose if we
347. 17:08want to do any uh client size scripting
348. 17:10or server size scripting instead of just
349. 17:12opening the module we can use this
350. 17:13background scripting service know where
351. 17:15we can uh it's like a we can use that
352. 17:18for a testing purpose
353. 17:20also okay so it's you said the client
354. 17:24side and server side so is it applicable
355. 17:26for both or oh no only for Server site
356. 17:30yeah server site okay so have you
357. 17:33created one have you tested anything
358. 17:35there yeah suppose while writing any
359. 17:38code and we want that to be tested
360. 17:40before or uh before submitting that
361. 17:43exactly in then then we will write the
362. 17:46code in the uh background script and
363. 17:48verify then and then we will use that
364. 17:50all if we facing while debugging also we
365. 17:53can use this background script okay uh
366. 17:57so suppose you have a code Cod of around
367. 17:59you know 500 lines okay there is a
368. 18:03schedule job which was written and it
369. 18:05has around 500 lines so I want to debug
370. 18:09that code that 500 lines how you debug
371. 18:12means what are the ways you debug that
372. 18:14particular
373. 18:16script we can keep this break sorry we
374. 18:19can keep this break and we will uh
375. 18:22validate accordingly uh that may be
376. 18:24little easy than going uh to the code
377. 18:28and
378. 18:29L okay
379. 18:31okay great so you have used it break and
380. 18:34all right yeah okay great and what about
381. 18:40reporting uh reporting uh I didn't
382. 18:43worked on much but I I know little much
383. 18:46about it yeah okay so uh you know what
384. 18:49are database
385. 18:53views you mean that uh for any form the
386. 18:57views that one no no database views
387. 19:01database
388. 19:03view we create in service now database
389. 19:05view
390. 19:08right you have not worked on database
391. 19:10view that's okay no
392. 19:12problem uh okay
393. 19:16so okay tell me one more thing uh the
394. 19:20difference between record producer and a
395. 19:22catalog
396. 19:24item okay so uh in catalog item we use
397. 19:27this part and then once we submit this
398. 19:30uh catalog item we will uh the request
399. 19:33will be created and for that request RM
400. 19:36will be created but for record producers
401. 19:38it will directly create a
402. 19:41task in the table level yeah in the
403. 19:44table okay it will not use any card
404. 19:48something okay okay great and uh in cogs
405. 19:54we can uh attach the workflows but in
406. 19:57recall producer we cannot attach but we
407. 19:59can trigger that in script we can
408. 20:01trigger the workflows in script great
409. 20:03great uh good answer okay so uh one last
410. 20:08thing yeah what is a scoped application
411. 20:12and what is This Global and all this
412. 20:15scoped can you tell me difference
413. 20:17between This Global application and a
414. 20:19scoped
415. 20:20application yeah scoped application is
416. 20:22like a unique application that was
417. 20:24created only for that uh to deal only
418. 20:27with the specific application uh suppose
419. 20:30uh people are who are not a part of any
420. 20:33uh project or who are not part of that
421. 20:35application couldn't able to uh make
422. 20:38changes or can view this application it
423. 20:40is only for security purpose we should
424. 20:43use the scoped application whereas
425. 20:45Global is for everyone they can able to
426. 20:48see this view this and can able to edit
427. 20:50this so majorly we will use the scoped

429. 20:58I'm done uh with the discussion uh can
430. 21:02you provide me a feedback like which
431. 21:04where I I can improve and where I have
432. 21:06to improve so that can be helpful for me
433. 21:08for the my future learning also sure
434. 21:12sure see the points which I have noted
435. 21:14till now is that you know whatever you
436. 21:17mentioned in your
437. 21:19resume like whatever you have written so
438. 21:22you must have some idea about that first
439. 21:24of all right and prepare best examples
440. 21:29okay for each and everything let's say
441. 21:32integration sorry when someone ask for
442. 21:34integration you must have though you
443. 21:36have not worked on it that's okay but uh
444. 21:39you must have a fair idea what are the
445. 21:41components of integration why we are
446. 21:43doing integration okay so if you have
447. 21:46written in your resume then you have to
448. 21:48be at least one or two examples so you
449. 21:51can prepare these things well in advance
450. 21:54and what you mentioned just focus on
451. 21:57that okay rest all things are fine you
452. 22:00are confident and you are you know
