I applied online, and the process took 3 months.

There are different rounds of the interview at Juspay, which are:

• Online Round
• Hackathon Round 1
• Hackathon Round 2
• Technical round with the senior developer
• Technical round with CEO
• HR round

In the very first online round, they ask 3 questions on graphs related to each other. In the second hackathon round, there was a question related to graphs. I did that, and then after that, they asked me to solve the same question with multithreading and all. I did that as well. They asked 50 to 60 cross questions on your solution, and the hackathon round went for 7 hours in total, starting from 11 AM and ending at 6 PM.

Then, after two days, I got an email from them that I got selected, and after that, I went for another technical round. In this round, they asked like everything. They expect you not only as a programmer; they asked you questions even on telegrams which were used in old days. That guy asked me questions like I had to create a keyboard and how did you make it, like seriously that guy really asked me any questions. Most importantly, I am a fresher, and how can any company expect from someone this much system design when the pay is only 8 LPA. Even Amazon does not ask these types of questions when they are offering like 25 to 30 LPA. It was the worst experience ever.

This process takes around 2 to 3 months because I always got an email just 1 day before that the interview was postponed, and it was postponed 3 times in my case. So, if you want to get selected, prepare everything, even software, hardware, how to build a rocket, everything; they will ask you any questions in further rounds.

Anything else that comes to their mind, like how to make a rocket or how to make the internet if the internet is not there, seriously.
