It was 2-3 weeks from the day I sent the job application until they answered but, in the meantime, a nice auto-response email was sent to me, with cheers and tips to make my CV more attractive. Then they answered me with a nice "we liked your portfolio" message and a selection test proposal. I sent back my acceptation and a couple of days later I was sent a link to the test. Now it's been a week and I'm waiting for the result.
