You'll get a test to do on your own time.

This test will consist of 3 hours of medium or less LeetCode-type questions.

Following this, there will be an HR phone call.

Next, a phone interview with some development questions and one coding question that is not hard.

The final round is 6 hours long, split between 3 coding questions and 3 behavioral questions, with the possibility of some system design.

The coding questions take too much time to properly complete. By the time I was done asking questions to clarify what was needed, I was already running short on time. Two of the three coding questions required a lot of clarification. I think they could have spent less time on my resume and more on the requirements. They need to frame these types of requirements first, instead of only having me read and ask questions. Once you notice you're running out of time, it leads to bad decisions. This is not how we work in the real world. You want to reward people for ensuring they are following requirements, not pit them against a clock.

All the interviewers were professional and nice, though.

The first question, for a stock trading algorithm, was framed poorly. The graphics provided suggest things that are not true. I did ask, and it was clarified, but overall, it was just not framed well. I normally don’t have such a hard time figuring out requirements. It’s honestly a straightforward problem, but something about the presentation takes too much time to clarify.

You should remove this question or explain it better, please.
