Bluestone Interview Experience for SDE (On-Campus) 2023

This was one of the last companies who came on 25th November. It was paying quite well (27LPA base) and also had only resume shortlisting. Meanwhile, it was only circuital, but I majorly preferred CSE as I gathered information about it. I researched about the company… it was a 2011 startup and good work was carried out there. I felt that I will get an interview shortlist as I had a good resume and..good internship. A good resume with a good internship + decent CPI + good academic achievements and programming achievements will play a major role in these types of shortlists. I filled out its willingness, and I got an interview shortlist.

Interview:

There were two rounds of interviews.

Round 1:

Duration: 30-35 minutes approx.

It was an online technical round. It started off with straight 2 DSA and coding problems.

I was asked to code it on a document shared by the interviewer.

Questions:

One was based on counting the number of ways to climb n stairs if, at any point in time, it can be 1 jump or 2 jumps. Standard dp problem ( easy)

It was also a dynamic programming problem. Given a number n, find if n can be formed as a sum of a combination of Fibonacci numbers till n.

Example: N = 10

Fibonacci no.s till N = 1 ,2 , 3 , 5, 8

The answer, is Yes 5+3+2 = 10

It asked me a little bit about OS and basics… what is mutex? What is deadlock…what are semaphore and race condition.

The Round ended with me asking about the company and what responsibilities are there in full time.

Round 2:

Duration: 20 min approx.

It was an HR round. The CEO of Bluestone himself took this round. He asked me about two puzzles that were a, little difficult or tricky. If it strikes then it is ok.

Remember, while solving the puzzle in an interview..just try to communicate what you are able to think at the moment don’t think for too long. Mostly, here the thought process matters even if you don’t reach the right answer.

[Here, also due to the recession, they reduced the number of hires to 3 and didn’t waitlist anyone. If there was a waitlist.I might be the first one there. As my interviews were quite good…one offer was also rejected, but they didn’t take it into account.]
