Interview Preperation

This is a extensive list of questions for both interviewers and interviewees when Servicenow Development is involved.

Interview Preperation

So interviewing is exciting.  It’s a way to get uncomfortable and see what is available in jobland.  Something to keep in mind, interviews are a way for you and your employer to find a great fit for this position.  The employer may be happy to have you, but you may not be happy in that position, so it’s crucial to get information from the interview to tell you about the technology, team, and the expectations they’ll have.  The expectations should have been set on the job posting, but it’s good to ask specifics about any you question. With that being said, when the technical questions are being asked, you should be able to see they understand the question and answer.
