Lame company, avoid. Recruiter wouldn't respond after multiple emails giving dates and follow ups. Then claims they were waiting for my dates (which i have provided multiple time already). Two coding rounds scheduled on different days. They ask to bring your own IDE ready! But the first one is system design (misleadingly set up as coding by recruiter). There are two medium to large system design questions for an hour interview. It was mentioned at the start the first question should only be 15 minutes. And the engineer who did that was rude, condensing and somewhat stupid. I get the communication is part of what they test, but after a certain point it goes both ways. Interviewer would keep changing the requirement to make the answers wrong. A system that handles duplicate business requests later becomes a legacy system where Kafka has to exist but somehow cannot be touched in anyway and so everything i mentioned about producer side prevention using idempotence attribute etc until then is wrong, duh! Now introducing new requirements or changing criteria is usually a normal way for interviewers see trade offs and multiple solutions, but here the interviewer was very clearly only doing it to later say the initial solutions were all wrong and wasn't even what they were asking for. Asks things like "Can JSON really have array attributes?" (it does?! - misleading and confusing) and later says "I was actually just pointing at the syntax on what you wrote down for it, it was missing a closing braces". Frankly although i had some good pointers i was a bit tired already before the interview and wasn't doing my best too, except it was clear anyway it was me who was dodging the bullet. Interviewer would not offer any time answering any questions about the company or him despite being a start up! Cuts off the call abruptly saying "Ok, I will pass feedback. Good luck to the next round tomorrow", not even a "we are close to the end of time" or anything like that. Looked at teamblind reviews later and understood what is going on.
