Sonatus Senior Software Engineer interview questions

Dublin Ireland hybrid role. Recruiter was a pleasure to speak with, very easy to talk to about work-life balance, comp and really experienced talking about the product. I couldn't tell if I was talking to a PM or a recruiter at times Spoke with senior SDM on West coast. Had to set up a call Irish time to align with Seattle which was out of hours for me. Not ideal but no way around it

The process: 1. HR screening 30 min. Quite a usual one. The recruiter told about the interview process, the team, and so on. It is supposed to be 1.2 coding interviews, System design, and culture fit. (However, as it turned out, it was not true) 2. Live coding 1h. I would say it is quite usual as well. Not so difficult coding question from leet code. 3. Live coding with a not-so-difficult question. However, the interviewer's hints were leading to the wrong approach. I'm not sure if it was intentional or if the interviewer didn't check the right approach before the interview. At that stage, i started suspecting that something was not right about the company. 4. I thought it was supposed to be a System-Design-like interview. However, it's more experience-focused, with some questions about the approach to projects and a small coding question. I had a feeling that the interviewer was forced to conduct the interview right before the interview with proper preparation. 5. This was supposed to be culture fit + experience talk. However, the interviewer started literally interrogating me about the smallest details of my previous work, which is a product closely similar to Sonatus's (such a coincidence). This was not just experience-related, it was really questioning how the algorithms work. I had to say I cannot reveal such details. In my opinion, the interviewer was trying to pull the NDA information of my previous company.
