i only wrote a 3 hours test (Which feels like 5 hours) from VZAP. The test is very general. It's not programming per say. it's logic. anyone can write it.

Once you get past the resume check / screening process you will get a link to a online assessment. This can be done using most common languages. The assessment contains 8 questions, some of which are debugging code and others just writing code. Not too difficult but you’ll have to be fast as you only have 90 minutes to complete it
