They have total 4 rounds.
1.HackerRank Assessment
2. Coding questions that cover DSA,threading and oops concepts,collections and SQL(one qstn from each of the concepts).
3. Same as second Round but the difficulty level increases.
4.Then Techno Managerial round(this entirely depends on the ED taking ur interview, for me it was all techncial and above my level of experience questions. but some of colleagues were only asked about their projects and some basic tech questions.)
Questions d'entretien [1]
Question 1
Case expression in SQL.
Unique character question in DSA(i don't exactly remember but the first round qstns would be on the level of longest zero sum subarray, duplicates removal)
For collections I was given an impl of set and was asked qstns abt its' behaviour.
And there was multi threading qstsn and oops question as well. The time would be too less to answer all these but you can try to show your knowledge and it would be considered.

The initial screening was an online assessment conducted on the HackerEarth platform. The test duration was 120 minutes and consisted of 8 questions in total: 5 MCQs, 1 SQL query challenge, and 2 Data Structures & Algorithms (DSA) coding problems. The point distribution was heavily skewed toward the coding sections (DSA problems were 100 and 50 points, SQL was 25 points, and MCQs ranged between 2 to 6 points each).

At first there are 2 technical rounds mainly focussing on coding, then there will an ed tech round, post which there would be some client interviews which can be more than one as well, and finally its HR round

Round 1 was as normal only like hashset hashmap questions related to what happen if we take object as a key to hashmap pre condition check should be immutable object should and equal and hashcode should be written properly then what if we return 1 to hashcode how it will behave what if update object post insertions how map will behave then character frequency dsa question immutable class and rest full form what rest api do then round 2 difficult output based inhertiance questions two three and then what id we remove @Service annotation with component and then inventory only one stcok senario based like what happen what sort of db lock etc operation you performed then questions of rotate array from k positon then a stupid questions of number to word very edge case question i explained the approach but didn't comeup to solutions so not selected
