I was once rejected by this company. So i was like now i want this offer weather i join or not.
DSA Round :
The round was pretty easy i would say the easy level probelm on linkedlist, Solved it by using Fast and slow pointer second one was on binary tree to traverse it by depth. Interviewer was very good and polite. He asked me about my projects worked on what motivates me and stuff like that.
System desgin Round :
This was again a classic example of Food Delivery, He wanted to desgins API's and Tables and stuff like that, He asked me that will there be a single point of faliure, DB scalling, DB sharding. Honsetly i have not worked on stuff like this, But by viedos and reading blogs you will get to know how to answer this.
System desgins went well, He said at this level you are doing too good and stuff like. I was very confident i will make into further rounds.
This Guy was like having 20 years of experince, He talked me tell me about a challenging task that you have saved some time and money for company, What motivates you, Are you ok to work from office and stuff like that.
After one week i got a mail that i am selected, 70 % more than what i was getting in present company. But i was recently went into some intresting project which i could not leave at that time, I did not join.
