Tesco Manager interview questions

The hiring process was very negative. I had a rude interviewer who had not read my CV at all. The worst bit was when I ran through my career history and mentioned I worked for a foreign company, the interviewer clearly showed disgust. Struck me as biased and surprised me that British companies like Tesco, nowadays, are not even making an effort. All these slogans of celebrating diversity are a lie, the truth is that Tesco only prefers employing ethnic minorities to fill their low-pay, low-rank openings. Manager and the levels above are out of reach and preserved for white British people only, and this is the case and exactly what I have noticed in their HQs.
