Vidio Data Engineer interview questions

I think there are 4 steps in total, but I failed the 2nd technical test. 1. Online coding test You'll be given a task to do. It mostly contains programming logic and SQL. Not so hard. Must complete within 5 days. 2. Coding interview It's about unit testing (Java). You'll be working with a Senior Dev to create some test cases. I failed here :( Advice: make sure you study unit testing. It's a bit "free", that you can add your own test cases but then add the required functions/attributes in the tested object class in order to receive the desired results.
