TCS Codevita Interview Experience (September – 2020)
I am an electrical engineering student. I solved 1 question in TCS Codevita Round and got rank aroung 7k. Got call for an interview on 15th September, 2020. You will get instruction around a week before interview.
Interview begins after some document verification with 3 interviewers :-
Lady HR :- If we give you night shifts, so will you be interested to work.
Me :- I had not directly said “Yes”. I gave reason that it will take time to change my habits. ( HR said you should be adaptable to the working scenario of your organization ).
Techical HR :- As you are from electrical, so what is your favourite subject ?
Me :- Data Structure and Algorithm
Technical HR :- What is the height of a binary tree ?
Me :- log2(n) ( He said whether n will be odd or even ). I said it can be odd or even we have to take ceil of this. So, finally i said ceil(log2n).
Technical HR :- Ask approach to convert a given infix to postfix expression.
Me :- I explained using two stacks, he said its partially correct. I forget about the precedence of operators at that time.
Techniical HR :- Tell me about types of linked list and difference between them ?

Managerial HR :- He again asked me that ” Are you comfortable to work in Night Shifts “. I dont know what they want to hear, I said him “Yes”. He said dont say ‘Yes” in pressure just feel comfortable and then answer.
