Software Development Interview Experience - Hong Kong, China
Process
I applied online and received an email a few weeks later from a recruiter for a technical phone interview, which lasted for an hour.
I got a response within days; they invited me to an onsite interview where they conducted two interviews, each lasting approximately 45 minutes, involving coding on a provided laptop. I stumbled for a bit trying to find an efficient solution. The interviewers were friendly, guiding me with possible improvements and pointing out edge cases.
I received an email a week later stating they would be looking for other candidates.

Although some people are trying too hard to fit into the "we are very nice people" mindset, and it shows they don't actually mean it.Cons: Experience in OCaml is a con because it is not used much elsewhere in the industry. Did not give proper feedback upon releasing the offer decisions. My mentor had way high expectations for an intern who is new to the codebase and language.
