I just tried out codility since I love tests. It is easy ... the test took under 20 minutes, about half of which I spent understanding the totally artificial logic of the problem (+1 for realism) and the other half I spent fixing the three very basic mistakes I made in a ten line function (1: order of operations mistake, 2: forgot to break out of loop, 3: forgot to "continue" to avoid rest of loop.) I didn't even think about performance since I thought they were bluffing but they do actually measure it. You can see my results here: http://codility.com/cert/view/certEF9FPJ-USWZ7H5WCSMSBNQX/details http://codility.com/cert/view/certEF9FPJ-USWZ7H5WCSMSBNQX/de... I'd say this type of test is absolutely reasonable and a time saver. Rather than spend 20 minutes doing a binary search or whatever on a screen share at a certain time that you have to plan your day around I think this actually saves time for both parties.
