Mission interview questions

It was pretty good. I had 2 interview within 15 days Managers were kind and the process was straight. They gave me feedback right away. We discussed about my background and challenges

I had an introductory interview, followed up by an introductory technical interview. They then kept me wondering for three weeks, until I finally told them they must have moved on. They were kind enough to email me back saying I was right. However, it was quite rude of them to keep me waiting for 3 weeks after an interview with no word on updates.
