I recently interviewed with Gemini. The round composed of 1 HM call and 4 onsite round.

Round 1 : HM Call
This round was based on brief discussion on my previous year projects and onee coding round. Requirement for coding round was to solve in one go,i.e. one you press "Run" button, it should not give any error or wrong answer. Question was easy and implemented the solution and was able to solve in one go. Question was "given a string like a3b1 expand it to aaab"
This was elimination round, cleared it and went on onsite.

Round 2 : System Design Round
In this round, i was asked to build crypto dashboard. The interviewer was only intrested in API design and DB Design and stopped me when i was going for HLD design. I gave the API and DB Design. I also solved bonus requirements using Redis Sorted Set., Interviewer confirmed he was happy with the api and db design. Interviewer was expecting brute force approach but i gave the optimised solution using Redis Sorted Set. Few System design terms like "Skip List" he heard for the very first time from me. Interviewer was Frontend Engineer.

Round 3 : Pair Progrmamming round
In this round, one coding question was given and skeleton code. The question was : "Given exchange rates, convert given currency to USD". Solved the question and interviewer manually verified the answers. The reason for manual verification was because of decimals in the test cases. My answers were correct but because of decimals, the test case were failing. Example - for one test case answer was interger 10000 but my solution gave 10000.0 . For another test case the answer was "12.45" but my code gave "12.4521000". Another test case has answer "52.67656". There was no uniformity in decimal place. Input params were integers.

Round 4 : Product Sense Round
Went over my past projects. How i navigated complex situations.

Round 5 : Behavioural Round
All questions were "Tell me about the time..."
Answered it honestly and gave answer to counnter questions as well.

Got a call from HR that my technical rounds were not good. I am still scratching my head on what went wrong as in both rounds, the interviewer was happy in the end. For System design round, the interviewer himself stopped me for HLD diagram and was happy with API and DB Design. Even for one second if i consider coding round was bad because i failed to see how many decimals to append, i cannot accept the fact that my system design round was bad. Recommend everyone not to interview with Gemini Crypto.
