Coding Technical
It was meant to be a multi-stage interview process. This included a take-home assignment, a call with the recruiter, two interviews over Zoom, and then a three-part on-site interview. I only got through the first Zoom interview. I felt like I did well on it, but two days later, I got an email saying I wouldn't be moving on to the next one. I'm not really sure what went wrong or why. It would have been nice to have more transparency, especially since I put a lot of time into the take-home. Also, the recruiter mentioned it would be a Leetcode-style question in TypeScript, but the actual question wasn't like Leetcode at all (I also thought it was strange it had to be in TS). The interview questions themselves weren't that hard, but it feels like a pretty long process for a company that isn't very well-known, especially compared to FAANG or big tech companies. It seems more appropriate for a startup.

Behavioral Technical Coding
First, there was a phone call with a recruiter where we chatted about my background and the company. They also asked about my salary expectations and explained the interview steps. After that, I got an assessment. They said it would take about 2 hours, but honestly, it took way longer, though I did finish it. It was a React.JS and TypeScript task, and they didn't give much time to complete it. Once I submitted the code, I got an email saying they weren't moving forward. I thought there were supposed to be like 6 more rounds, including an in-person onsite, which sounds like a really long process. It wasn't a great experience, and when I asked for feedback, they didn't give any. They got back to me super fast, under a day, which makes me think they barely looked at my code. That felt pretty disrespectful.

Coding Technical
I did a coding assessment first, and then an in-person interview which was pretty tough, with algorithm and design questions. The recruiter was easy to schedule with, and I liked doing the coding assessment on my own time rather than a phone screen during work hours.
