I would highly recommend to stay away from them. What stood out the most for me - that the office was empty - without any employees. They also said that everyone left them (and even said they felt deceived by the previous employee) , When I asked them where all their workers were - they said that they had one employee that left to to found a new company. After a short investigation - I found out that it wasn't true. That employee left for another developer job and apparently they had other employees that left whom they didn't mention to me. Red flag anyone? They will also create a very strange contract based on options. No professional/ technical questions were made, Looked extremely unprofessional. When I asked about the choice of technologies - one of them insisted in using specific technologies that might not fit the best practices. (The answer was: "I'm used to working with x").
