Applied online.

Phone round initially with a team member. Courteous and friendly interviewers.

Got called for an on-site interview in 1 week.

Met with 5 technical team members and 1 HR recruiter for interviews at the San Diego campus. Long day, lots of questions and coding challenges. Did well in coding challenges, but they require better, in-depth answers to conceptual questions.

Bit manipulation questions:

• Detect pattern of ones
• Write masks to insert a pattern of ones in a 32-bit integer

String and array manipulations:

• Reverse string
• Reverse words in a string
• Find duplicates in an array

Concepts:

• What is virtual memory?
• What are caches?
• What is priority inversion?
• What is reentrancy?
• Semaphore vs. Mutex
• What are spinlocks?
