Tactable interview questions

it is a small company in Toronto, I had 1 interview and had data cleaning questions using pandas, and some other questions related to normalizing the data etc. make Sure to be completely comfortable with the syntax.

Interview process included initial screening round but haven't heard back, then after a week once I followed up and they gave me take home assessment based on typescript and dependency injection. I have completed and submitted assessment on the same day but haven't heard back from 2 weeks and then I followed up with an email but didn't get any reply from there. Very unprofessional! I hope I hadn't waste time completing assessment.
