IBM Entry Level Software Engineer interview questions

Was sent the IBM coding challenge a day or two after I applied. The challenge consisted of 7-8 questions: 3 were coding problems that you have to solve & the remainder were a mix of behaviorial & verbal technical questions that required webcam responses. This challenge lasted about 4 hours, despite the email saying that it would typically last 2-3 hours. Two day after I completed the challenge, I was notified that I passed and could go for a face to face interview the following week. The face to face interview was via webcam with a senior software engineer and was an hour long. In his own words, there are no right or wrong answers during the interview. Instead, he was more interested in my personality and thought process. The interview was mostly about my interests, the extent of my knowledge in certain areas, one whiteboard question, and one brain teaser. A week after the interview, I was notified that the position was given to someone else.

The process took about a month. I applied online and received a Coding challenge invite. The test duration is for 3 hours. It has a few behavioral questions and 3 coding questions. The coding questions are based on string manipulation(one similar to FizzBuzz, one similar to finding common substring, one similar to finding lowest common ancestor in a tree). The test will usually take the entire duration allotted. The second round is a live digital interview with one of the technical folks. I was asked about my previous experience and projects worked on after which I was asked a coding question. The question was based on recursion and dynamic programming.
