I didn’t apply, their HR found me on LinkedIn. The whole process took about 3 weeks. There were announced five interview stages: The first meeting with hr, who found me. It lasted 30 minutes and involved questions about my previous experience. I was told that I would be a perfect fit for the company. The second meeting was with another hr. It also lasted 30 minutes and involved the same set of questions. The third meeting was with someone from the engineering team and a co-founder. It was planned for 45 minutes, but they gave me the last 5 minutes to ask questions, so it lasted more than an hour. They asked about my current job, team, and responsibilities. The fourth stage involved a technical task. They said it shouldn't take more than 2 hours, but it was impossible to complete within that time. They told me that if I couldn't finish it, I could write my ideas about how I would approach it. I spent quite some time on this assessment and even completed the parts that were stretch goals. I also wrote documentation about the project’s architecture with some ideas for improvement. I was given this task on Thursday, and on Friday, hr called to arrange the next meeting at the office with the team for the following week. This was arranged even before I began the home project. She asked me to send the homework at the beginning of the next week, so I did it over the weekend. On Monday, she called again to ask if the task was ready. She also told me that the next meeting was planned for 3 hours: 1 hour with the engineering team to discuss my home project, system design, etc., 1 hour with the design team, and 1 hour with a co-founder. After I sent the project, they never got back to me. On Thursday (a day before my next interview), I wrote an email asking if my home project met their expectations and if we were still meeting tomorrow. I got a response in the evening with a plain answer that I was rejected. I asked for a feedback but was ghosted. I was quite upset, not because I was rejected (there were already a few red flags for me by this point), but because I didn’t have a chance to discuss my project, explain how I would improve it, etc. These people don’t care about your time, don’t respect your effort, and don’t even bother to give you feedback.
