Recruiter reached out to me to see if I was interested in a developer role on one of their teams. I responded back and an initial HRese type interview was scheduled followed by a 1 hour call. There was 30 minutes with the hiring manager as well as a 30 minute code challenge.

It seems like PagerDuty is more concerned with hiring individuals who can pass HackerRank type quizzes instead of hiring engineers with real experience. They are yet another Silicon Valley company that doesn't know how to interview senior engineers.

Hiring manager asked questions related to my previous experience and exposure to internal tools they use like Docker.

Code challenge was as other reviewers have mentioned:

Find a pair that adds up to a 100 - with an added requirement not to remove any duplicate pair.
