I applied through a recruiter. The process took 2 months. I interviewed at Proofpoint in Feb 2025
Interview
The interview was lengthy. I've met around 8 different people at Proofpoint. All but one of them were really nice and experienced. The remaining person was very sure of a programming language implementation detail although he had it wrong, even explaining it wouldn't help, so I wouldn't consider him very open to suggestions or comments.
Interview questions [1]
Question 1
There were many instances of interviews, three about system design these were easy. Three were algorithmic exercises in code, these ones were of medium-low difficulty, a good understanding of data structures is enough for them. The remaining two interviews were to discuss impactful contribution on previous jobs, nothing out of the ordinary, just extremely lengthy
