Culture Biosciences interview questions

applied online via linkedin (i believe). a few weeks later i get an initial invitation to interview via phone screen with an HR rep from the company. HR rep was calm and relaxed but did seem rather stressed; you could hear it in her voice. apparently a lot of sr management had been let go (including her boss) and abrupt changes had been made. so positive on point with her transparency in regards to this matter. she did mention she would get back to me on friday, and this is true, but it was a rejection email. the main reason i give the negative response is simply the obvious "free consulting" questions that were asked. they are looking for leads or solutions to their current issues for FREE under the guise of a "job interview." this is EXTREMELY unethical and speaks volumes about the company culture. so based on that, i would pay HIGH attention to the company reviews that are in the 1-2 range because they most likely are the valid reviews.
