IBM Software Engineer - Full Stack interview questions

A coding challenge through hackerrank, and a video call interview. Both were very reasonable. The hackerrank involved a full-stack type of question (involving HTTP requests), an algorithmic/dynamic programming question, and a very open-ended question which they said would be reviewed by the hiring manager (no test cases for that one). The interview itself was somewhat nonstandard for a coding interview, as it did not involve any coding at all! The interviewer just asked me behavioral and background questions for the whole time, which I found very interesting. The process was very quick; the interview was scheduled within a few days of me completing the hackerrank, and I got an offer the day after my interview. (However, this may have been in part because I interviewed in April, which is fairly late in their recruiting season, so they were probably rushing.)
