BrightBytes Analyst interview questions

I had a 30 minute phone interview and then got invited to do a technical task prepared for me via e-mail. The phone interview consisted of their introduction of the company, and my personal and professional interests. I then had a follow up technical task. I am disappointed that I did not receive an e-mail at the very least informing me that I did not get hired - it would have been a minimum courtesy given that I completed the technical task. I even requested feedback, but not response.
