I applied on their website.
First Round - Interviewer was an SRE
Lots of questions related to every day work. Debugging, k8s, docker.
Used an online IDE for 2 easy LC questions - no test cases as such, just asked to run the code
Second Round
Used an online IDE with test cases present. Question related to reading files + parsing + sorting
Was allowed to google. Interviewer was friendly. Went well, gave hints when I got stuck
Third Round
Design ride sharing like Uber - only services. Was easy, got over quickly.
HM Round
Normal HM round, asked about my current role and responsibilities, what to expect from okta. Interviewer created a very relaxed environment
