Systems Engineering and Assessment Ltd interview questions

I was phoned and emailed by one of their 'talent aquisition BPs'. After research I told them I wasn't interested. I then got an email from them telling me I'd 'withdrawn from the recruitment process'. I didn't go into their recruitment process in the first place - this is evidently some con they're running to bolster their own recruitment metrics. Avoid.

Interview was with two people who asked a lot of technical questions, if I was in this situation how would I handle this etc. I felt they were trying to make me crack under pressure. Contacted the agent afterwards and informed him this job wasn't for me due to the way I was interviewed
