Unlike you I have actually met him, and I think he is the right man for the job. I do not know the purpose behind your anger towards Erik, but if you think he is the wrong man for the job, don't criticize him criticize the people that hired him. If Solomon and Sandberg hired the wrong guy, then blame them not Erik.Once more you are barking at the wrong tree.
I know that Erik has worked for at least one of the companies he lists in his profile. Don't know for how long but I am sure of this because he answered when I called the company once. I have also met him in person a few years ago. But I do not know him.
Actually I can see that company on his linked in profile. So I can verify one of the companies he worked for.
I have not read all your accusations but I do believe that he is a bright person at least. Yes Nils Sandberg likes him, but probably mainly because he is a competent analyst.
Also it seems like two of the short internships were as a summer intern. But yeah it seems like he switches employers quite often.
