Shopify Sr. Software Engineer interview questions

I applied through the Career portal after seeing an ad on linkedin. I got invited for a technical screening round directly without any conversation with HR. They give information on what to expect during the interview. The screening happened quickly and knew of decision in 24 hours. Based on the expectations provided in the link prior to the interview you need to solve the given problem. The interviewer was from Canada and I was interviewing for a Berlin role. The interviewer didn't know that it was my first face to face interview with shopify without initial HR screening. So he was trying to break the ice and gave some info about the company for first 10 mins. Then for next 45 mins he gave me a coding exercise to be done over coderpad. He started off saying that the problem was extremely simple and nothing too complicated and that he wants to just see my coding abilities. As mentioned in their link, they also said they are looking for how well I collaborate. I asked a couple of clarifying questions before proceeding. So I explained my thought process and presented my option and he didn't say anything other than yeah sounds good. I asked if I should start coding and he said yes. Halfway through I was explaining and told him to let me know if he thinks I am rambling and not clear on what I am trying to say. He looks again at my code and was like yeah yeah I *think* I understand, keep going. And then I was stuck and I was asking I am not sure what I am doing wrong here. He absolutely had no track of what direction I was going in and was just lost. When I asked for hints, instead of driving me away from the wrong direction I was going in, he gives me an approach based on the solution he already knows about. Now which means I have to reset my current thought process and start over again. And then I thought, oh wait, it doesn't look like the solution is as straightforward as he said at the beginning of the interview. And this made me even more nervous when getting stuck and overall I failed to complete the exercise. Another thing was, he kept looking on a different side of the screen and every time I asked a question he would turn his head, meaning he didn't really seem engaged in the interview and wasn't collaborating. In my opinion, I think he just setup incorrect expectations right from the start and didn't really try to understand what I was proposing and collaborate with me. I have conducted several interviews myself and I know that if I can't follow what the candidate is trying to do and steer them in the right direction, it means I wasn't paying enough attention and collaborating enough.

My interactions with the recruiting staff were great. We had a video call and everything was very exciting if lite on details. After that when I started speaking with members of the actual engineering organization I was shuffled from interview to interview, my questions about the compensation range of the position were dodged and I ultimately decided not to continue without that information.
