A week ago I had a first stage interview. I’ve worked at four companies each for around 4 years each. The interviewer asked me lots of questions around whether I’d ever fallen out with a colleague, whether I had always got on with people generally and went into detail about why I left each company. There’s nothing suspicious in my background but I have in the last few months had a huge clash with a manager. I’m now worried they know something? I also didn’t disclose this and wonder if that now means I’ve technically lied?
