After applying, I received an email from the recruiter to select a programming language of my choice for an online assessment test. I chose C. The questions were multiple choice, primarily on output prediction and memory allocation types.

Then, after a week, I received an email for a phone screen. The phone screen questions were technical:

• Write code to add commas to an integer, e.g., 12345 would become 12,345 and 1123 would become 1,123.
• Design a vending machine. What data structure would you use if you want to count the occurrence of each word in a dictionary?
• Some basic resume-based questions.

After another week, I was invited for an in-person interview. They took excellent care of me, including flight booking, hotel reservations, and airport pickup.

I had one technical round with two developers. I was asked to reverse a string in place and remove spaces, so for example, "Software Eng " would become "tfoSgnE".

I was also asked to create a data structure for the appendix of a book and to discuss my current work.

Now I am waiting for their answer :)

Write code to add commas to an integer. For example, 12345 will become 12,345 and 1123 will become 1,123.

Reverse a string in place and also remove spaces. For example, "Software Eng " would become "tfoSgnE".
