The initial interview was over the phone with the director of sales. He asked standard interview questions like "tell me about yourself". The call was conversational we spoke for about 20 minutes. My second interview was with the account manager not too long after my first call. We spoke for 40 minutes about the job, opportunities and introducing ourselves. The third interview I gave a mock product presentation to the "client" (Director of sales and another employee) at the company headquarters. My last interview was with the CEO over the phone. He asked basic interview questions and others like "do you have any concerns about the company or position?". Overall, in my opinion everybody was professional and friendly. It seems like a good company for entry level professionals to grow in their career.
