IBM Senior Data Scientist interview questions

Interview Process: The process began with an initial screening where HR seemed quite positive about my background and experience. They discussed the role in detail, and the conversation left me feeling confident. In the following rounds, I had interviews with the technical team, covering core topics in my field, and I felt I matched well with their requirements. Throughout these stages, I received encouraging feedback, which built my anticipation. After the interviews, HR indicated that things were moving in the right direction and that I could expect an offer soon. This led me to believe I had successfully cleared all rounds and just needed the final confirmation. The entire process seemed aligned with a positive outcome, which made the wait exciting. Feedback: After a couple of days, I was shocked to receive a rejection email instead of the expected offer. The email was a standard rejection with no specific feedback, leaving me frustrated and confused, especially after the earlier positive signals. It’s disappointing when feedback contradicts what was initially communicated, and I’m left wondering if there were internal reasons or last-minute decisions behind the change.

I was at the first technical screening round, where I was asked to solve two tasks on HackerRank. It tooks ~1hr, and I submitted with all tests passed. However, I never heard back, not even for an automated rejection. The recruitment team should be more respectful of applicants' time.
