The interview is entirely too long, with people who seem completely uninterested. You're essentially interviewing for five jobs that you could potentially have. Several of the interviewers relied on other aspects of the interview process to make a decision about whether to move forward.

For example, during the portion with a project manager to design an API, if the design is too technical, they will rely on the coding portion to decide to push the candidate to the next phase.

The coding problem isn't challenging; it's probably on LeetCode. As a seasoned engineer who uses an IDE, using a browser-based editor is challenging. You don't have a feedback loop as you work through the solution, as you would in real life.

I don't remember what question they asked me.
