I had an onsite job interview for a software position at a German startup, which included brainstorming at the whiteboard on how to solve a problem. I should hear back in a few days.
The problem is quite challenging and I ended up writing some code to solve the problem they gave me, as I got some insight/ideas on how to proceed. I don't know how good or bad the solution I developed is, to be honest. I made a few tests and it works, in first approximation.
Is it bad policy to contact the startup CEO showing the results I got? Am I coming as arrogant or disrespectful (people probably spent quite some time on these issues..)? On the other hand, after their decision the value of the test code I wrote goes to zero. Any feedback is welcome.
