IBM

Asked some design pattern problems, data structures, and multi-threading. They also asked to introduce working experience, the problems encountered, and how they were fixed.

They let me introduce myself first and asked me some questions about basic programming concepts. They didn't ask me any difficult questions. A manager asked me about my working experience and introduced his department briefly.

I had technical and managerial interviews. I applied for other jobs online. Somehow, I received a call asking me to try an interview at IBM. So, I went there and had the interview.
