I have been asked 1 question in first round, I couldn't complete it in one hour.
for second round the interviewer had some extra time so he took 2 questions + 1 Leadership questions.
The questions resemble with the following questions:-
1.1) https://leetcode.com/problems/number-of-islands/ :- Here instead of island, I was told to count the number of cluster of buildings, where we can assign one Amazon Go Shop. Solution is the same.
2.1) https://leetcode.com/problems/rotting-oranges/ :- Exactly Same
2.2) Given a string s consisting only of characters a, b and c.
Return the number of substrings containing at least one occurrence of all these characters a, b and c.
Input: s = "aaacb"
Output: 3
Explanation: "aaacb", "aacb" and "acb".
Input: s = "abc"
Output: 1
2.3) Describe a time when you took on work outside of your comfort area. How did you identify what you needed to learn to be successful? How did you go about building expertise to meet your goal? Did you meet your goal? (LP- Learn and Be Curious)
My third round was cancelled. I don't know whether it will be scheduled again or will be cancelled.
If it is cancelled then I am rejected otherwise the game is on.
I will update, if 3rd round happened.
Thanks guys.
Update 11/02/2022:-
Done with 3rd round of the interview, I was asked multiple questions in this rounds.
3.1) Design an Object oriented parking lot. What classes and functions will it have.
It should say, full, empty and also be able to find spot for Valet parking.
The lot has 3 different types of parking: regular, handicapped and compact.
3.2) What is the difference between sql and non-sql. How will you decide which one to use?
3.3) What is TTL? How long does the data remains in memory application?
3.4) How will you troubleshoot for the Memory Exceeded Error? Follow up question with real time situation.
3.5) Tell me about a situation that required you to dig deep to get to the root cause.
3.6) Tell me about a time when you had significant, unanticipated obstacles to overcome in achieving a key goal.
It was pretty long interview and was good going. Pretty positive but earlier Interviews will decide the final output.
I will keep you posted.
