Arriving late can leave a poor impression & make the interview question your reliability, so make sure you are on time for the interview, if you are unsure of the location it is best to plan your journey in advance and take a trip early to familiarise yourself with the location, if you are doing virtual interviews make sure you have good connection and log in 15 mins before hand to avoid any technical problems. If in the instance you are experiencing technical glitches let the interviewer know so that they are well prepared and have a back up in which you can use an alternative way to do the interview such as via your phone or download the communication software on your phone.
