Deel Senior Software Developer interview questions

The company required personal information, such as documents (residence permit, etc.), during the first stage of the process (screening) - without signing any kind of contract or agreement stating that my personal information would be safe with Deel.

The introductory conversation with HR went very well! The process, company and roles were described in details and all my questions were answered. But. this HR lost my homework assignment -_- Right after the intro call, you get a homework assignment that needs to be completed in a week, but it's stated to take no more than 3 hours. It is actually complex and you have to tradeoff to complete it even in 5 hours. After submitting the task and then checking back a week later, I received no response. Nothing... I had a person at Deel contact this HR and only then did they find my email and review the assignment quickly. I was disappointed with the review. Their mentions of approaches were mostly wrong, but the major red flag I got on rejection - potential SQL injection, was correct. So that's fair, probably. But they didn't mention my advanced approaches, such as database denormalisation and indexes to significantly improve query execution time. They don't seem to want witty engineers, but resilient ones who can do standardised work.
