It was one of the worst interviews that I have had in my life. I was advised to complete a home work (3 days). As a full-time professional, I suggested during the week that I would prefer doing this at the weekend. We agreed. Unfortunately, something came up in my family (health issue, emergency). I kindly let the recruiter know about it in time apologising for the circumstances and suggesting that I would complete it early next week instead, so literally within a few days. I got a response that "This is truly disappointing. Your reluctance to undertake our simple C++ test is a cause for concern and undermines our confidence in your application. So it is with regret that I have to advise you that we will not be progressing your application further. " I mean, seriously, it is just life. Sometimes, issues happen. Clearly, not a flexible environment. They would not even accommodate emergency. I honestly recommend anyone to think twice. I have since then got another interview proposal from them since that HR person left (or was let go, apparently was an HR contractor according to LinkedIn). I do not regret it though as their wage was below market value even for a mid-level software engineer, what to speak of Senior.
