Servicenow Technical Interview questions

[Community Alums]

Hi there,

Recently I have attended for an interview for ServiceNow developer role. These are the few questions that I haven't answered. Please help me with these...

1. How do I control access to variables on portal?
2. Difference between catalog item and record producer.
3. Diff between field and variable
4. Diff between Ui action and UI policy
5. How many ways can you create a field?
6. How many ways can you trigger a notification
7. Can I use GlideRecord API both in client and server scripts?
8. How can I disable a change type? (Suppose I want to disable standard change type)
9. Write script that logs Number of incidents that are active and category = Hardware and priority = critical. Print all the Incident numbers as well.

I wrote this:

var gaINC=new GlideRecord('incident');
gaINC.addQuery('priority','1');
gaINC.addQuery('category','hardware');
gaINC.query();
if(gaINC.next()){
gs.log('Number of incidents: '+gaINC.getRowCount());
gs.log('Incident numbers: '+gaINC.number);
}

10. When should you use GlideAjax?
11. How many ways you can attach a workflow to a catalog item?
12. Table name of schedule
13. How can you set timer activity in workflow to run only on weekdays?
14. How can you migrate schedules from dev to test?
15. Change vs Release management
16. I have a notification that goes to a group. All group members receive the notification except one. Why the only member didn't receive email notification? How do you troubleshoot this?

Hi there,

A few questions?! This is a huge list! How long was the interview, you can't cover all of this in 1 hour?

Anyway, can you specify your real questions a bit? I mean, search a bit, Developer Site, Docs, Now Learning, and you know the answer on many of these already. Then ask again the questions where you have doubt on, though also explain why you have doubts on a certain question, etc..

If my answer helped you in any way, please then mark it as helpful.

Kind regards,

Hi @Mark Roethof 

Yes the interview lasted for more than an hour. I have answered to many of these. But somehow the interviewer is not satisfied with that. That's why I'm trying to find reasonable or satisfactory answers for these. If you ask me to select the questions that I don't have the answers I can say  questions 1, 8 and 14. 

Please give me an answer  for these.

Sure it can happen that the interviewer was not satisfied and you did not succeed in the interview. Though then just ask the interviewer for feedback, so you can learn from it.

For example, you are not mentioning the script from 9. The script is incorrect, the interviewer should be able to give that as feedback to you so you can learn from it.

Also like I mentioned, ask the interviewer questions. Like what I mentioned about workflow. This will show that you know more about ServiceNow, though this way you can also feel if the interviewer is actually knowledgeable or just ticking off a standard interview list.
Or like "Change vs Release management", that's not a question. Ask the interview what the question is in more detail.

If my answer helped you in any way, please then mark it as helpful.

Kind regards,

And reading questions like these, also ask questions back in such an interview. IF someone asks you:

11. How many ways you can attach a workflow to a catalog item?

13. How can you set timer activity in workflow to run only on weekdays?

Then either the interview is outdated, or the interviewer might not be so knowledgeable themselves. Or they might ask this on purpose, to see if you mention something about the preferred method of ServiceNow nowadays, which is not workflow.

If my answer helped you in any way, please then mark it as helpful.
