Wildfire Systems (CA) interview questions

I had an initial interview with the hiring manager and although I thought it went well, I never heard back from them. I followed up twice, but still no response. It's disappointing to have taken the time to prepare and show up for an interview, only to be ignored afterward. The fact that they didn't even have the courtesy to send a rejection email shows that they don't value their candidates or their time. It's frustrating to see a company that seems to only care about filling a position and not about the people they're hiring.
