I applied on their website, then received an email from a Technical Recruiter saying that he tried to call me without success, asking to arrange a new call, and for an updated copy of my CV. I replied to his email and provided the requested information, and since I was on holiday outside of the UK, I suggested arranging the call via Zoom or a similar tool because my phone was off. To my surprise, he never replied to me, despite following up with him a couple of times, and even suggesting to arrange a phone call since I will be returning to the UK the following week. Very disappointing attitude.
