Barracuda Networks Software Developer interview questions

I applied to the company during career fair in the university campus. They contacted me a month later. They asked questions ranging from sorting to network theory. They also test knowledge of makefiles, dynamic programming, OS fundamentals. They also tested knowledge of statistics. There were total of 4 people, and afterward, vice manager came and told me how the company operates and why I should work for them. They told me that they will inform me about the result at most a week later. But they did not inform me about the result. They did not event send a mail stating that I am rejected. It has been 5 months.
