Received an email from a recruiter asking to schedule a Skype interview, confirmed date with HR. Interview was short but we connected well and I showed my interest and enthusiasm for Number26 and their product. I even introduced them to Acorns as a potential expansion idea. I was then assigned a challenge to complete which the recruiter said shouldn't take me more than a few hours. As such I didn't try to reinvent the wheel but to focus on design, attention to detail (like creating an app icon and such to go over and beyond). To my disappointment, I received a generic rejection email from HR and subsequent attempts to contact the recruiter for feedback went unanswered. I think this burns a bridge unnecessary and Number26 should take the time to detail what was missing just in case there are future opportunities for collaboration. I feel I would have been a great fit given my interest in finance and technology and my background. I grew up in Berlin and speak fluent German which would have been an additional advantage.
