3 stage, email test then telephone call then face to face meeting. The email test took about an hour to complete i think and covered JS PHP and database tech. The JS was a nice one, you basically design a little app and demonstrate elements of code opposed to writing a full on app, after the process i learned this was to demonstrate how i thought as well as basic proof i could code haha! The rest was just standard interview techniques, the telephone one threw me a little though, there was a bunch of fundamental coding tests in there like "what is the difference between const var and let and when to use one or the other".
