MAQ Software Software Data Operations Engineer interview questions

I applied online and was contacted by one of the recruiters at MAQ Software. I had to answer a questionnare consisting of 9 questions about my background and some general behavior questions. Then, I had an interview on-site. I had 1:1 interviews with 3 people, all of them were senior software engineers. First person tested me DSA and SQL problems, like in leetcode, but had to write the answer in hand with paper and pen. Second person asked me simple DSA question and a probability related math problem. Third person asked me how I would develop a software given a situation. The overall process was okay. BTW, before the interview start, you will get the books that the CEO wrote, so if you want the books, you get them free.
