Applied to Maven security they were quick to respond with a hacker rank coding test with 3 questions. Having spent a few hours on the test, my answers passed all but one test case. After submitting, i was rejected the next day the reason being that i did the test in python, total waste of time. If you want someone to do the test in a specific language i think it's common knowledge to let them know beforehand or restrict the test to only that language, i was given the choice to code in python or c#. I could have done both, but thought python would be much quicker to code in. Programming languages are just tools they don't determine whether you're a good programmer.

Applied online. Online assesment. One question was on TMP and the other on implementing some kind of matching engine. Done on hackerrank. Submitted with all testcases passing but didn't hear anything back.
