IBM Software Developer interview questions

This was in the middle of 2017. They rescheduled THREE times for the initial technical phone screen. Interviewer was late for technical in-person interview at a coffeeshop. Long wait times all around, and they seemed to be more learning about what I was doing rather than testing me. They asked a lot of questions about design choices and specifics about the tech stacks I worked with like they hadn't really heard of them. Finally, the recruiter asked me to come to an onsite after that last in-person interview and later said that she forgot I had already met someone in person but that I should come in anyway. I'm sure some of these aspects have changed by now, but the process was very messy.

This is my first interview, I struggled a little bit and I did select in it. I come after three years of completion my degree that is the reason I didn't select for job.
