Good interview session but structurally felt like a start-up environment, I could see that there is a strict low-communication hierarchy there, people tend to stick to their laptops while on the floor and there is a slight feeling of "keep your head down" in the office. Salary non-negotiable and the HR lead was brushing through the conditions of employment probably wanting to seal the deal. I had ended up pointing my finger at my phone where I had calculated what the amount I was requesting was, she kept repeating the annual before-tax amount (that I was going to see half of) and I kept repeating what the after-tax offer was. The amount offered was low for London... taking rent into account and the office location on Lloyd's Avenue and just how generaly expensive London is...
