I understand your concerns, but how you suppose to check, lets say secondary team members if they pass your tests fine, have linkedin profiles and are willing to work for you? I did personally chatted with Einar or whatever his name is. I personally is happy to provide video of myself or anything like that.
No, after i found something wrong with team information, i will not believe that project. In today life, people using HD picture on his LinkedIn to make Job seeker hire them. But, your team just giving low resolution of this photo, why?
What! you are hiring people to join your team, but you are "not sure" about his name?
Thats your choice and I respect it. I did an interview but did not request video conference call, will do that in the future. What I'm trying to say is that I'm a founder of a company (you can check company details), I employed someone without due checks and now I found out he is possibly not a trustworthy person. All I can do is to remove him and not to deal with him anymore.
