IBM Software Engineer interview questions

Very swift, efficient and effective. Quick call from HR to organise which was very pleasant and a reasonably challenging but enjoyable interview. They were 2 people, trying to get the best out if you. No BS.

IBM is the worst company. I've completed 4 rounds of interview i.e 3 assessment,2 phone interview,1 behavior round. I've not received any updates from the recruiters.I've dropped several emails but got no response. They literally don't ask a candidate interview slot but assign according to first come first serve.
