Basic questions about SQL, C#.Net and how to execute basic queries.
C#, .Net and SQL Questions.
Required to take a written exam, where I was to complete calculations for travel expenses. The exam was given like a high school math word problem. Was tricky to complete because I was unfamiliar with these types of calculations at the time.
First interview incorporated technical questions, with schematics. Simple questions, but symbols are of European background.
I would say the most difficult question would be the one a person doesn't know. The interview process is only to find people that are suited for the job. If a person doesn't know the answer, it's likely that person hasn't prepared for the interview or isn't capable of doing the job.
there was no any unexpected question from me but for others there may be.
