Soft Machines interview questions

Very slow interview process. Started with a phone interview, then couple of onsite technical. Followed by meeting with VP and CEO on different dates. Whole process took close to 3 months. Starting from the phone interview there was rescheduling etc. So not very professional. Interview questions were good and appropriate. Some of the technical staff gave good feedback and were open. So, some positives there. But overall, not a good experience, slow and unprofessional.

All the interviews were techincal. There were 2 phone interviews. Since I was saying far so there wasn't any on site interview. However. The first interview was of 1hr long but the 2nd went on for at least 3 hrs and 45mins. It was tough and was asked about the OS and processors. However at the end I screwed up. So wasn't selected.
