Urgently interview questions

This company's interview process was a joke and needs great improvement. Their hiring manager contacted me first. He said it would be a 30 min chat. Well I assumed some casual intro for a given time slot. But then this HM apparently wearing a snapback hat in an interview showed up and was pretty terse throughout the interview. He finished his intro and then he paused. I was waiting for his queue to start mine but he exactly said "go ahead". What a rude opener to an interviewee. Then they gave me a take home assignment which was not bad. Just had to formulate how I make a model for their dynamic pricing problem. Then I was invited to their 1-hour "onsite" which was split to 45 min chat with their team members and 15 min chat with their chief data officer. The 45 min chat was nothing more than behavioral, just chatting casually here and there about what my thought is on an end-to-end ML problem and if I am familiar with AWS, etc. This team chat was ok and I liked the interviewers. But then their CDO was a bit of a jerk. She showed up and did not give any intro about herself and straightout jumped to some of the behavioral questions (how would I prioritize things, how to handle different ideas, etc) but all in 15 mins. Obviously she had to go over time a bit and did not apologize for keeping me over time with her asking questions over and over. 5 mins past the alotted interview time, she asked me if I have any questions and I asked 1Q only because of the time constraint and she didn't look happy enough that I was not willing to stay over time. Haha. Overall, negative experience and wonder about their technical competency given the "easiness" of the interview loop. Nothing technical. Also, the HM's vibe was not going with me and I am glad that I did not get selected TBH.

It was a 3 part process, the first being a typical behavioral/culture fit call with the company HR rep which was great. Lots of information and the work Urgently sounded interesting. The second was another behavioral/culture with the VP of engineering which also went great and got good vibes about the overall culture and direction leadership was planning to take. The third part was the technical interview with a Senior Java engineer and a Lead engineer. This is where the wheels fell off in the process for me. Both were not on camera despite a remote first company (which is fine internally if that’s your culture but for an interview?). When the first interviewer joined they weren’t very personable (no problem I can sit in silence staring at the camera). When the second joined we started immediately and they gave some mediocre introductions stating their name and the team they were on (your team name means nothing to me as an outsider give me some substance). Next they asked for an intro from me. Then I was asked an SQL question about how to select certain columns, join a table, and format the date. Then asked how to make some Java classes immutable (seems odd but figured it might lead somewhere other than general Java trivia) and the first interviewer was done with questions. The lead took over and we started the coding challenge where we had to remove duplicate LinkNodes from a sorted list. At this point I wasn’t quite sure how to go about it since I hadn’t worked on these data structures professionally and saw them in college (my bad for not prepping I guess?) but managed to provide some solution with a Set/Hashmap but they didn’t want an extra data structure. I then managed to stumble the rest of the way to the solution they wanted and spoke my thoughts as I went. After taking most of the time with the challenge I was cut off an told I can ask questions of them. Asked about culture and how the difficult the vacation policy was to utilize etc and was met with short answers or long pauses trying to think of a professional answer.
