After the initial screening, you will then be invited to the assesment centre at the company. You'll have a group assessment where you solve a problem with assigned fellow applicants and you will also have an individual interview.
I applied online. The process took 2 months. I interviewed at IAG Tech
Interview
Applied online. 6 weeks later a recruiter scheduled a call - giving one specific time for the call rather than a range of options. The recruiter hasn't called at the agreed time. On follow up we've rescheduled for the next day. The recruiter had not seen the CV despite it being a part of the application submission. Next step was a call with the head of engineering with an HR person. No feedback beyond "thank you for your interest".
Start with series of online assesment, follow with a video recorded interview. the process took a little bit too long, It's been about few months still haven't heard from them.
