Positive ExperienceNo Offer
Process
I applied online. The process took 4 weeks.
Good people, very responsive and helpful. Very short rounds and quick process. It took me about a month to go through the entire process. Did not pass the technical challenge, not leet code style but situational coding.
Questions
API and SQL based. More towards code correctness than LeetCode.
