It is highly suspect if the invitation is just to fill up the local citizen quota.

It is a rule set by the Singapore government that by interviewing local candidates and failing them, the organization can then hire foreigners.

This was a typical software array coding question, not customized for the role.

The interviewer's English was not fluent. He typed in Google Docs to ensure no miscommunication. The questions were not answered properly. He appeared to be working from home and was potentially speaking with his wife.

I ended the session quickly, rather than spending more time on what felt like an insincere and not entirely legitimate interview.
