3 technical + 1 HR round.
Some interviewers are nice, some are basically unprofessional.
Things like being late, not turning camera on, and not trying to clarify his questions.
My overall impression is that they are simply looking for someone who memorizes "concurrent programming in XXX", "5 ways to protect your service from huge traffic” and “Networking 101”. Read on these topics if you really want to apply.
They show little interest in system design and algorithm skills.
And yea got ghosted after the interview.
Can’t agree more on the comments around its non-employee centric culture.
The entire interview processes was a recruiter call plus three rounds of technical interviews. Interviewers were friendly. Technical coding questions and work related questions were asked based on your past work experiences. Each interview saved time for the candidate to ask questions.

Scheduled with recruiter. Scheduled and interviewed. It was well organized. Interviewer are good. HR, manager, hiring manager. Some of the interview organized around 8pm. Some of the interview organized around 8pm.
The interview process was well-structured and relatively efficient. It typically consisted of multiple rounds:
Online assessment / initial screening: Focused on data structures and algorithms, with medium-to-hard LeetCode-style problems.
Technical interviews (2–3 rounds): Covered core computer science fundamentals (data structures, algorithms, system design basics), along with problem-solving and coding in real time. Interviewers also asked follow-up questions to evaluate depth of understanding and optimization.
Project discussion: Detailed discussion of past projects, including design decisions, trade-offs, and real-world impact.
HR / behavioral round: Focused on communication skills, teamwork, and cultural fit.
Overall, the process emphasized strong coding ability, solid fundamentals, and the ability to think clearly under pressure. Interviewers were generally professional, though the difficulty level was on the higher side, especially for algorithm questions.
