The cutoff was 7.0 GPA. I was eligible for the Online Test.
There were 4 rounds in total:
Round 1 – Psychometric Test: The process started off with a Psychometric test(50Q in 12 minutes). Candidates who clear this test, have to go through the online assessment.
Round 2 – Online Assessment: It consisted of 10 Tech MCQs(OS, DBMS, CN) , 10 Quantitative Aptitude MCQs along with 2 coding questions. Aptitude questions were of easy-medium level. Managing time is the key here.
1. Minimum number of 1s that are needed to express a positive number in terms of special number. A special number is a number that consists of only 1s. Example: 1, -11, 111… etc.
Input: 32 Output: 7 Explanation: 11(2 1's) + 11(2 1's) + 11(2 1's) + (-1) (1 1's) Input: 19 Output: 5 Explanation: 11(2 1's) + 11(2 1's) + -1(1 1's) + -1 (1 1's) + -1 (1 1's)
My understanding: It looked like a Coin Change problem with negative coins. Although I went in that direction, it didn’t work. I skipped this question.
2. Simple hashmap question
I cleared the online assessment along with 46 other students(who applied for various roles). I was shortlisted for a physical interview.
Technical Interview – I: It lasted for around 30 minutes.
Puzzle question: Print the sequence without using a loop Input: 16 Output: 16 11 6 1 -4 1 6 11 16 Hint: Use recursion

I couldn’t arrive at a solution for the Pairing Problem, even though the interviewer gave a few hints. He told me to give it another try for some 2 minutes, because he told me that I was close. When I asked him for feedback at the end, he told me “For the role you have applied, you have good DSA skills”. I thought I did well, until the moment they announced that I was rejected.
Technical Interview – II: I got to know this from my friend who cleared the previous round.
Apparently, it consisted of a design round. The question was to design an E-Commerce website. They asked only the approach and a few questions like “If a user hasn’t logged in and wants to buy a product, how would you redirect him?” etc.
My experience: It was my very first interview and I had hoped that I would clear it. Although I did around 290 problems on LeetCode, I was unable to solve just one question due to which I was rejected unfortunately.
Don’t give up and keep practicing : )
