This is a overview of the whole process and how it took place the whole proceess and you will get a fair idea . How swiggy hires Offcampus

I will explain the whole process and your questions will get answered overall through this.

Round 1: Shortlisting
I was quite active on LinkedIn and suddenly appeared a post from a person who had shared a google form for Internship at Swiggy. It was not specified whether it was backend or frontend or sde . But I just filled it and I had been quite active and hardworking so my resume got shortlisted and I received a Online Assessment Link.

Round 2: Online Assessment
No of Questions : 4
Time Alloted : 60minutes
Difficulty of the Questions: Medium to Hard
Key to Clear: Make sure you attempt all the questions even if your all test cases are not passing and also make sure you don't complete the assessment so fast that they think you are overqualified for the role.
I had been doing dsa and cp for around 2year and so I didn't find it too difficult.

Round 3: PSDS Round
No of Questions: 2
Time Alloted : 60 minutes
Difficulty: Medium (LC) but constraints were twisted by the Interviewer
Key to Clear: Communicate with the interviewer from the starting 1 minute and make sure you are on same page with him as he will be the one who would be approving you to the next round so more than you he should understand your solution and problem solving skill

Round 4: Hiring Manager Round
Theme of the Round: LLD Round
Difficulty: Easy to Medium
Question and Key to Clear: Design Stackoverflow and explain each and every part to the interviewer and this is a thinking based round , How do you optimise the basic stuff as a backend developer and also how can you reduce the time required to run these operations.
I had a fair amount of practise of this round and also I knew this was somewhat coming as I had given interviews in firms where lld rounds were held. So yeah

Verdict : Selected
