The process involved a long and grueling online coding round. I think the second round was mostly technical, requiring me to record myself on a webcam. The third and final round was a one-on-one, primarily behavioral interview.

My experience was terrible because my recruiter was unimaginably awful. She was so bad that I'm turned off of IBM forever. This was very congruent with what many are saying about IBM; they truly could not possibly care less about you as a person.

One example: she texted me around 8 PM one night asking if I was up for the final round interview the next morning. I replied very explicitly that I was NOT available the next morning. Thirty minutes later, I received an email saying "Interview Reminder" or something similar, as she had apparently scheduled the interview anyway – during my midterm.

That's just one example.

Don't apply here. It's not only challenging and extremely time-intensive but also, frankly, just very bizarre. There are plenty of better companies with better opportunities and more reasonable interview processes.
