Biogen Administrative Assistant interview questions

I applied for this AA position online through Glassdoor and was soon reached by someone named "John Summers". My first red flag was his email address because the domain was biogenhr.com and companies do not give their HR departments their own domains. Nevertheless, I read his email and shock: he wanted me to set up a Google Hangouts interview. Another red flag was that he did not even acknowledge I had an application into the company - he just said that he found my resume on Glassdoor. Any HR person would have known I applied. But it gets better! I am pretty sure the entire job posting was fake because that's how they trap people and get your email address and everything. The company site does not have any related postings nor could I find anything about a Dallas location....another red flag. Folks.....let me just say, if you're applying for an Admin position, there is simply no way to "work from home". So, back to that initial email from John Summers. I looked him up on LinkedIn and there was no such person. Then I reached out to the actal Biogen Senior Recruiter to ask her if they ever conduct interviews in that manner and sadly she was not professional enough to respond back. It's possible she just had too many emails to respond to, but it has now been two weeks and I have still not gotten a reply. Not even sure that that's the type of company I would want to work for. Overall, not a good experience. I have no idea who posted the job posting and we need to know these things in order to report the fraudulent activity to Glassdoor. It wouldn't take more than a few seconds to reply. I've had similar situations where I received a personal email from the company before an interview request takes place. Beware of the scammers.

Received an email in regards to speaking with someone via google hangout. I added and ask if this was going to be setting a time for a phone interview, told me no that it was going to be on here via chat. After about 20 mins chatting with him, in which I was told at the start that I could not ask questions until the end. Also the position I applied for never brought up, and when ask this was for the admin assistant it was not answered. I was told that he was impressed and needed to forward my answers to the Head Dept, that it would take a few minutes. After 20 mins of waiting I chatted and ask should I expect to hear back from him today, no answer. I wrote back after a bit that I was declining any more interviews. Very Different interview process.
