I applied through their job portal. After a couple of days, the recruiter contacted me via email asking for a phone screening.

I had a 45-minute phone screen. After this, they emailed me again for an onsite interview.

The onsite interview lasted from 9:00 AM to 2:30 PM and included 5 rounds of interviews, comprising a 1-hour manager discussion and a 15-minute recruiter discussion. Most of the questions were about basic data structures and problem-solving.

After 2 days, I received a regret email.

How will you implement a word ladder puzzle?

1. Two sorted arrays are given. One array contains extra space so that it can accommodate the other array's elements. Merge both arrays in sorted order. Optimize the solution.

2. Design Redbox. It should be capable of adapting new resources without much code change.
