I applied through a recruiter. The process took 4 weeks. I interviewed at BT Group in Aug 2019
Interview
Small interview over Skype, after that 2 smaller design tasks in 1 hour to do so they can see how you can perform. The tasks weren't too difficult, but the time constraint makes it a challenge.
Interview questions [1]
Question 1
How long is your notice period? Can you negotiate it down?
