I applied online. The process took 3 weeks. I interviewed at MongoDB in Nov 2024
Interview
The interview process is well organized. Recruiter keeps candidate informed about the process, also an online dashboard is provided with interview progress, dates and names of interviewers. The first prescreening is standard DSA question. The code and a test case needs to be implemented and the code should run. Then the main stage, consisting of software design and coding tasks. The tasks are relevant to the position and require deep understanding of concurency, networking and other relevant topics. The interviewers are knowledgeable and friendly, it was my pleasure talking to them. I failed Part 2 of the interview, so cannot say what happens at Part 3 and Panel interviews.

I applied through an employee referral. The process took 3 weeks. I interviewed at MongoDB in Aug 2021
Interview
The interview process was pretty exhaustive, having several specific technical interviews (concurrency, algorithms, design...) and generalist interviews. They were tough but not overwhelming, the interviewers were helpful and made me feel comfortable.
