Do not invest your time

Look at the lower reviews as they’re true, these people will poach you on LinkedIn to fill out qualifiers to get you access to consulting opportunities. Reality is, there are no clients who are looking for advice on their strategic issues. GLG will lead you on, you will not get calls with their clients, and at best your data is being collected. This site may have once been legitimate but today it is a scam service.

Waste of time for consultants

It’s honestly getting ridiculous. Every time I’m asked to participate in a GLG paid survey, even when I respond immediately, it either tells me the survey is already closed or runs me through vague screening questions before deciding I’m “not the right target.”

This has happened at least six times, and I have never once actually participated in a survey. There is zero follow-up and nothing but boilerplate responses. It’s a complete waste of time and extremely frustrating.

GLG Experience

I love these consultation calls because they give me a place where my real-world experience is the product, not filtered through sales politics or vendor messaging. I can speak honestly about how things actually work; the broken handoffs, bad assumptions, margin leakage, and presales blind spots. And it’s energizing to be treated like a strategic peer instead of just another quota-carrying engineer.

Professional teams

Professional teams, strong communication! However, the team doesn’t tell me until I accept the call that the client wants a discount or prorated fee.

I’ve added to my profile that I do not prorate and require an hour minimum, no
Matter the length of the call.

GLG is a great company to work with

GLG is a great company to work with. The experience is pretty great and the surveys come often and GLG does an excellent job of only sending surveys that I actually qualify for as opposed to other compaies that send out everything and hope that something sticks. I think that's great for both the company looking for data (they get real and useful data) and the person getting the surveys (we don't waste time filling out surveys that we eventually don't qualify for). All in all, GLG is great to work with.
