Tesco interview questions

I applied online, all the process is really slow. after the application, you have to answer an online assessment, Ive got an email a couple of weeks later saying my application was being processed, i really though they would never call me, they did after a month! it was a face to face interview, the manager kept writing down my answers, the manager was friendly and the interview went well, easy questions and the manager didn't caught me off guard with the question because i studied a lot. Ive been told I would get an answer in 4 weeks. I didn't get any answer, not even an email, or call just to give me some feedback! its ridiculous, not very professional, it seems they do this a lot. shame on Tesco!
