This was one of the most dispiriting interview processes I ever went through. I reached the middle stage. Although the initial screening call was straight-forward, all of the emails I got from the recruiter were automated, including the one telling me I was unsuccessful.

 There was no reply to my request for feedback. Confidently I would say do not bother applying, there were too many things amiss.

5 stages interview with different managers. Casual dress code. Final stage requiring a PowerPoint presentation. Business organisation split between mainly the US and UK office. Hammersmith location (not the best location for tech company).
