IBM Graduate Software Engineer interview questions

It was quite straightforward, at least until the second stage where I got dropped off. The first stage was an interactive gaming online assessment where you had to go through some challenges. For the second stage, I got a form and was asked to fill it and submit it. I filled it, submitted it, then got a rejection email about two weeks later.

First there was the IBM online test involving linear algebra and numerical sequences. After that there was the face to face interview with the recruiter. I got rejected that phase so don't know what's going on next.
