The interview process began with an easy phone interview, followed by an onsite interview in Chicago.

The company provided a flight, hotel, and a debit card for other expenses, which was greatly appreciated.

The interview process was standard:

• Two technical interviews in the morning.
• Lunch with the hiring manager.
• Three more rounds of interviews in the afternoon, one of which was purely behavioral.

The interviewer was typing notes throughout the entire conversation.

Whiteboard coding topics:

• malloc and free
• Single-producer, single-consumer message queue
• Multi-thread implementation for calculating the average of numbers from many files in parallel
• Relatively easy algorithm questions
