multiple45-55minutes Interviews (some was via video), really difficult. Combination of behavioral, algorithmic, computer science, and system design. Unlike companies like Google, they tested heavily on computer science knowledge.
0.5 round is some screening with behavioral questions.
First interview on a leetcode hard algorithm problem with some more computer science fundamentals.
Second interview on system design.
The third interview was given 1 medium difficulty algorithm problem followed by a combination of security, networking, operating system, and database concepts.
Didn't make it through afterward, probably more rounds if I had passed.
