Interview
I applied for their contract role through a headhunting agency. The recruiter contacted me after three days of sending my CV.
She went mute for a week then out of the blue the hiring manager sent me an interview invite with two days' notice.
I had to revise on the concepts for less than 48hrs. Some of the things I had forgotten from my post-graduate study.
There were two interviewers, one sounded like an analyst the other one was the developer.
