First a technical phone interview, then 2 in person interviews - followed by a final decision. The first two rounds were reasonable, the final interview round was unclear and didn't have much direction in terms of what they wanted as a solution. Was a single question based on the implementing the sliding window algorithm, but the instructions were unclear and wasted a lot of time in clarification (not in a good way).

Partial behavioral then technical interview. Questions mostly consisted of clarification of side and school projects, showing application towards the job. Technical interview is typical easy leetcode question. Interview was one hour long with a response within 1-2weeks from HR.
