There were 2 main rounds with the Manager, named "Phil" in their London office. After the interview they called me to inform that we are happy to offer you and would share the official offer in a day or two. I contacted them in 3-4 days regarding the official offer letter and the recruiter said " we've 2 positions to fill so we are finding the best skillset that matches yours". I chased them for weeks and they always said that you are our first guy because of which I had to put my other offer on hold. Finally, I was recently told that they've hired someone else. It's good that you hired someone else but it's a request that you value a candidates time and please don't commit on something you can't deliver.
