Chatham Financial Full Stack Software Developer interview questions

Overall the process was pleasant and what I consider to be ideal when job searching. First-round was an online assessment using CoderByte. The problem was to create a password validator based on certain requirements. If you know how to code then this is simple enough. The second round was a technical assessment with two senior developers. The two guys were very nice and made for a pleasant interview. Here they asked typical interview questions and went over the resume. Lastly, there was a screen share where I had to solve a Leetcode style problem. (LC Easy. L20. Valid Parentheses). They were very encouraging and gave hints as needed. After solving the problem, they asked questions on how would I optimize the solution and other tweaks.
