Clever Devices Software Engineer interview questions

These were the steps of the process: 1. Online application 2. Take-home exercise 3. Technical Phone Screen 4. On-site Interview (4 sessions) 5. Phone Interview with VP (preceded by two preparatory phone calls with HR) 6. 10 days later still no follow-up from Clever Devices, so I badgered them for two days until they finally made closure. After steps 1 or 2, it was obvious that Clever Devices is a very third-rate company, but I went along with the interview process for the sake of due dilligence. The mediocrity of the developers who interviewed me confirmed that suspicion, and I decided I wouldn't accept an offer even if they made one. What infuriates me is the unprofessionalism on their part of not following up. This process took over 2 months, and I dedicated an entire day to travel to your HQ in Woodbury, please have the decency of following up.
