Coding Technical
For the technical screen, I was asked to solve a couple of coding problems. The first was about finding the length of the longest increasing subsequence in an array of integers.
Confirmed questions5 questions
- What's the length of the longest increasing subsequence given an array of integers?
- Can you optimize the longest increasing subsequence algorithm to run in O(n log n) time?
- How would you modify the longest increasing subsequence solution to correctly handle negative numbers?

Coding System Design Behavioral
The whole process had 4 rounds, and I unfortunately didn't make it past the third. The initial chat with HR and the first technical round went smoothly. They were pretty responsive and helpful. But, the second technical interview with the engineering lead was a bit of a downer. The interviewer didn't even turn his camera on and seemed totally disengaged, which is kind of a basic expectation for an interview. Also, I was hoping for more back-and-forth on the system design question, but the interviewer was really quiet, like he was doing something else entirely during our discussion.

Behavioral
Had a quick recruiter call, pretty standard. Got rejected a couple days later with no feedback. The role's been open for months, so it feels like they're looking for a perfect candidate. The recruiter talks up the company online, but the process was impersonal. I get I wasn't the right fit, but the role still being open makes me wonder if their expectations are too high. Maybe others had a different experience, but if you're applying, don't expect much communication.
