Process was straight forward. HR person emails you. Asks for the choice of language. Then sends you programming question. You have about a week worth of time to submit, but once you start you have to do it in one hour.
They scores you based on how long it takes to solve the problem, don’t think they even look if your solution is working or not. If you say it took you more than 30mins then i think HR person is going to send you response saying you’re not selected or something in that line, no more explanation.
Overall good experience.
