This happened 3 years ago in my previous company. It was a small start up company and we worked on PHP stack. One of the its ex-founders had written Windows Mobile App which now had to be upgraded with new features. So we hired this new dot net guy. I always thought dot net guys were ELITE coders and was excited to see how they work.
While I played Xbox and had fun, our dot net guy stuck to his workstation furiously working. My boss who was casually strolling out of his office for a stretch saw dot net guy working hard and suggested we all developers should take him as an example.
20 days went by and each day the dot net guy did the same. He came, he silently worked on his workstation, he left in the evening. In those 20 days my boss asked twice to the dot net guy if he has finished features he was assigned but he said he did not. After a month when he said the same negative answer and had nothing to show for the work he has done he was fired.
I was so curious to see what code that ELITE coder had written for a month but could not deliver a feature(Maybe some error he could not fix?). So I open the code repo on which he worked and I see 30 commits from that guy to it. He had made a single commit each day(Fair enough he wants to commit everday before leaving). It was time to check his commit diffs to see his ELITE code. What do I find? In every fucking commit he either added a blank line to the DocBlock or removed the same. Nothing less nothing more! So much for the hyped not-so-ELITE dot net guy...
