Lidl Area Manager interview questions

Applied through recruiter. Aptitude test (numerical, logical & verbal reasoning). Interview with recruiter. 3 hour interview 1 week later. First a group exercise, received a brief of 3 stores & best way to improve them, group discussion monitored by 2 Lidl HR staff. Individual speed interview, mainly situational questions. Followed by a written comprehension which included recommendations on spending an allocated budget to improve 4 stores.

Telephone Interview first where the Polish lady commented I didn't have much retail experience (I have 35 years, maybe she didnt know the English companies I have worked for), followed by a call asking why I had not replied to an email regarding a 2nd interview which I had never received. Finally the "interview" for 1pm was in fact 11 people being talked to for an hour before a 30 minute test then a several hour wait to be seen. I left at 4pm, this was the most embarrassing selection process I have ever been part of. I then sent their HR department a long letter detailing these issues, but no reply, only to be followed later by an e-mail from the Polish lady saying I was unsuccessful (er, you'll find I walked out of your process!).
