Applied online and was contacted by email by a Mr Lewis Milford. Quite interested in setting up a call, ask Cortana to book a time for us in the calendar. Turns out, the day of the interview about an hour before he decided that he was too busy and they would be getting back to me, obviously apologising for the delay. Still waiting to hear back but glad to see the level of professionalism

Difficult and technical interview process especially for recruiter job. Recommended but seemed a little strange to me. It has been a while though so not sure how it is now in current hiring and interview procedures
