I applied online, and the process took two months.

I did a technical phone screen, which was one of the most commonly asked hard LeetCode questions. After I passed that, I had an onsite that consisted of four rounds:

• A laptop coding round that was an algorithm question that also required me to write my own test cases.
• A system design round in which the interviewer and I designed a hypothetical system and discussed tradeoffs.
• A behavioral round in which a bar raiser from a separate team asked me standard behavioral questions.
• A domain knowledge round specific to cloud security.

One of the most commonly asked hard LeetCode questions. It is on the blind75 list.
