Get open-minded and prepared for any question! Straight immediately after one of my second interviews, I was required to stay behind and take a technical test out (I had to recreate the website example while in front of me from scratch). ‘Sorry my raise is waiting outside…’ or ‘the now, I wasn’t expecting this’ won’t decrease very well with them. If you are exploring a long way for this interview, give yourself enough time to get truth be told there relatively early (even if you sit down on the nearest café going over your info) and understand that these can sometimes go on for much longer than expected. I always found it helpful to record a list of future questions they could question me and I would study their basics, so there were no surprises.
