IBM Senior Software Engineer interview questions

2 rounds of coding. First round is mostly common dsa questions like implementing queue using linkedlist and some variations and questions about c++ stl. then the next round was more on a system level like how will you handle an infinite data stream coming from network. This round was interesting.

Smooth process with 3 rounds - 2 technical rounds with coding exercise and 1 managerial round. Another gaming round which probably was must as part of the process. Followed by HR discussion and Offer letter.
