The advisors were nice and knowledgeable. But the recruiters seemed rude and unprofessional. They would schedule interviews without asking for availability, change the schedule as late as 10 minutes before the meeting but not inform me about such last-minute changes. The process wasn't as smooth as some other companies.

Telephone interview. The interviewers were a research scientist and software engineer at IBM. They had reviewed my resume and GitHub account, and for the first half we talked about the experience/skills I had. The second half was the technical part, wherein I was asked an object-oriented programming question, an algorithm question, and a machine learning question.
