I applied through a recruiter. I interviewed at Cyberhaven
Interview
1. Recruiter screening - 30 minutes
2. Engineering screening - 30 minutes
3. Coding - 90 minutes
4. System architecture - 90 minutes
For the next stages, it probably depends. In my case it was hiring manager and someone from higher management.

1. 30 Minutes of recruiter screen - A discussion on previous projects and other behavioural questions.
2. 30 Minutes Technical Phone Screen - LC Easy/Medium with incrementing difficulty.
3. 1 hour machine coding + HLD - A basic log parser was asked, and was later asked to scale it to a distributed service.
4. 1 hour of LLD - Creation of a prototypal Version Control was asked. Focus on clean class structures, writing test cases and covering for edge cases.
5. 30-45 minutes of Hiring Manager discussion - Technical deep dive on your projects if necessary, and any behavioural concerns the Hiring Manager might have
6. 30 Minutes of Leadership Round with Head of Talent Acquisition - Mostly to check your cultural fitment with the organisation.

Interview
Fast interview process. Very technical questions. The team was very excited, interested, engaged, accessible. Totally a positive experience.
I spoke with 4 people and a recruiter. Each one knew the space extremely well. Thoughtful, in depth questions. Seems to have an upbeat culture.
