First, HR had an introductory call, asking about motivation to move, future career goals, and compensation expectations. HR was very professional and friendly throughout the entire process, making it one of the best interview experiences ever.

There were five rounds of team member interviews:

• Two rounds of coding, conducted via HackerRank on the phone.
• The second round had two interviewers.

Finally, there was a talk with a higher-level manager.

This interview took place in late 2021.

Coding session: Merge K sorted arrays into one large sorted array.

A list of words, without spaces. Write a function to make a proper sentence by inserting spaces. For this question, the interviewer asked me step by step, including the data structure I chose to use and why.
