IBM Software Developer - Entry Level interview questions

I received an email from IBM saying I was approved to take their coding challenge which took around 4 hours. The coding challenge included a video interview. You start with a video interview and you are given roughly a minute and a half to prepare your response and five minutes to record your response in one take. After a few interview questions, you move onto the coding challenge which consists of three questions which take about an hour and a half each.

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.
