They present the job to be very strategic, a role that requires skill and intelligence. However, in reality, the job is completely administrative and doesn't require much skill or thinking. I would strongly recommend looking elsewhere, especially if you are coming from an Ivy league (or similar) school.
This is a basic sales role, much like a glorified call center - where they are only looking to sell calls to their clients. They work is very mundane and administrative (constantly scheduling phone calls, sending calendar invites, searching for "experts" on the internal database and Linkedin, cold-calling throughout the day. There is no real research element in the job (unless you consider research to be doing searches on Linkedin), nor any sort of consulting.
For those saying this job gives you "industry knowledge". Well - if you think speaking to an expert for 2-3 minutes gives you some major insight into an industry - sure. But, in reality, most experts see Alphasights as a middleman (which it is) and want to minimize their interaction with them - so as to speak directly with the client. Essentially, the level of industry knowledge is extremely limited, and it cursory. It is also worth noting that 99% of interactions with clients and experts happen over the phone, so if you're looking to build any client interaction skills etc. - this role will not help with that either.
Additionally, given the nature of the job, you are constantly micro-managed throughout the day - and provide minor updates to managers on a throughout the day (e.g. called 10 advisors, left them a voicemail, emailed them, heard back from 1 of them etc.)
Coming to "managers" - most of them have 2 years of work experience, and are not necessarily people you would typically consider mentors or look up to. Their sole aim is to sell more calls to clients, and aren't necessarily intellectually motivated.
Finally, the compensation and benefits are significantly below industry standards - especially if they are trying to recruit from top schools.
