A couple of stages.
First stage is a meet and fit culture interview
If successful you will be given a take home code project (this is not for production so its not a way for the company to get free work)
1-2 weeks to complete.
If you manage to present a working project big plus. Lots of grads don't get something working in front of the company (Projects are pretty broad in scope so complexity is down to you)
You will be interviewed by generally 3 people when you present your project.
They will ask you why you chose certain tech over other tech, why you thought X, etc. Pretty standard stuff.
Interviewers are pretty nice and relaxed people but they know their stuff
