Purely DSA and language-based

• Firstly she checked the paper given by my previous interviewer and then after that she asked me to solve 3 sums I explained every approach, and she was impressed
• Then she told me to write the code of quickSort.
• After that one binarySearch problem (Search in sorted and rotated array)
• I answered every question with every approach she was very happy with my answer
• She asks about shell Scripting, the Bankers algorithm, Belady’s anomaly, and the round-robin scheduling algorithm.
• Then she asks about one puzzle (I know about that puzzle So I solved that )
• After that, she told me Jyoti answered everything and the previous interviewer had asked for your resume.
• Then she gave me one pseudocode of exception handling that was very easy i.e. based upon Parent and child classes of exception handling if we are using multiple catch blocks can we write parentClass in the first catch block and after that it’s child?
• Then after that, she asked about the internal implementation of hashmap, I explained to her with load factor rehashing with everything and writing the pseudo-code also, after that she told me that your technical is very good, but I’ll suggest I be calm because your next interview is professional fitment, so behave professional, then she does handshake with me and said Jyoti I’m giving your name for the next round don’t tell anyone.

And then she said any question.

Round 3 (Professional fitment round)

• She asked heap sort, I explained it to her, and she was watching my body language, my communication etc.
• Then she asked about the values of DB
• She gave me situational-based questions, depending upon your thought.
• I’ll suggest always using words like Learning and growing they want passionate learners.

Round 4 (HR round)

I was the last candidate (It’s almost 8 pm) So, they conducted my HR round online.

• Discussion of all project
• Team Management, again situation-based question.
• Every round is the elimination round.
• They announce the result by evaluating all the previous 4 rounds at the end.

Verdict: Selected

All the interviews were on the same day, They declared the result the same day after 9:30 pm, It was a hectic day but it was all worth it.

Be confident, and avoid bluffing in front of HR because they are very experienced be true.

Go through all the interview experiences, especially on GFG, and if you don’t know any answer simply say I don’t know. Research about the company because the last two rounds were based on company values etc.
