The interview process consisted of a total of 5 rounds: 4 technical and 1 managerial.

Everyone involved is very technical and will grill you on each round.

1st round: Generic programming to test your logic.

2nd, 3rd, and 4th rounds: UI Development specific. They were not interested in which framework (Angular, React, etc.) you have worked with. They primarily wanted to see your JavaScript knowledge, problem-solving approach, and communication skills.

5th round: Managerial. The manager explained their team's work. Afterward, they presented a problem and asked for your approach, discussing every point you raised.

All these rounds were completed within a single day, taking approximately 4 hours. The process was very smooth, and everyone was exceptionally smart.

Overall, a very impressive hiring process.

How will you approach if you were asked to design and develop a railway booking application like IRCTC?
