A very quick 30 minute video chat, which can be lovely based on the time given, but there is a lot of chat from their side, so you're not given too much time to ask questions. If that goes okay, you're given a really long 4-part assignment, asking for test cases, test plans, automation scripts, bug fixes, and re-writing technical specs. They have a scoring system internally so you'll never know which is weighted. Which means no matter what you can excel, one thing going wrong is enough to disqualify. This also means they can change the requirements on the fly to disqualify you and keep the work you give for theirself.
