Google Frontend Interview Experience | L3/L4

Question: HashMap + HashSet
Response: This was a very easy round for me , i completed coding + running different test cases in around 30 mins and i did not have much to ask so we finished in around 35 mins

Second question was 2-d array manipulation , finding paths related question.

Question: String manipulation +implement Somewhat Auto complete
This round was a bit difficult but at the end the interviewer was happy with me and we closed this round on a positive note by cracking some jokes .

This was a very hard interview , as Fe domain level went really deep , P.S the interviewer was an author of famous articles that i read before , so we had some really good interaction , FE domain question was more of implementing retry function and then from there we jumped to implementing promises methods (.then , .catch .finally) , talking about CRP's and ways to optimize it .

Question: More related to sequencing of tasks
Response: This interview went almost perfect, I had to write code in Javascript as that was my preferred language ,
Question was more of a topological sorting , but once i solved it , it was more related to promises and different methods of promises such as promise .every etc. to sequence the tasks in orders he wanted

I would say this interview went really well for me , i finished early

This round revolved around situations and how would I tackle it .
The interviewer wished me luck and i would say this round went well too.
