Questions posées lors d’un entretien d’embauche pour Software Engineer - Java Developer chez W.A.G. payment solutions

Not mentioning the fact it took quite a while for a person to contact me and set the interview up (despite having been told he'd contact me within a day or two after the initial call), the interview itself was probably the worst I've ever had in any of the Czech companies. The questions themselves were fairly easy and I'm not sure they should have even been asked in the first place (think stuff like difference between private, public, protected etc.). After I answered them well, the interviewer accused me of cheating during the interview. That is already a big red flag. After I was not able to answer the following practical question the interview was called off by said guy. I'd say his unprofessionalism reinforced my belief this company should be avoided like a plague
