A recruiter reached out to me on Hired. He followed up by scheduling a 15-minute phone interview. He then decided to move me forward to a technical phone screen, which was scheduled for a week later.

After that phone screen, I was moved to the virtual on-site, which consisted of four interviews:

• Two coding interviews
• One system design interview
• One bar raiser interview

During the coding interviews, I felt the interviewers were indifferent. They presented a HackerRank question without much explanation. I asked many clarifying questions, but instead of receiving answers, I encountered dismissal and indifference. Even when I proposed a solution and provided an example, no feedback was given, even after completion.

The system design round differed significantly from the coding rounds. The interviewer introduced himself, and we had a genuine discussion about the system he asked me to design.

The final round was what they call the bar raiser, where you discuss your past experiences.

Phone Screen: Implement a key-value data structure that uses timestamps (tip: use binary search).

First Coding Round: Parse input from STDIN and implement a password generator.

Second Coding Round: Parse input from STDIN and implement a function to give a winning hand for a card game. A winning hand consists of 3 cards that share all the same properties or all different properties.

System Design: Design a system to handle a shopper paying for a customer order.
