I joined GLG about 2 yrs ago and I have done dozens of surveys and a few phone interviews. The payment process is simple and I've never had an issue with being paid. The payment does take around 5 business days but its 100% legit. Highly Recommend!

Quite unprofessional in the way they approach possible consultants (Romil Gill). They (he) use(d) dirty tricks and outright lies to get me to register, pressuring me to complete registration ASAP because "the client wants a call with you and can't wait until Monday". After registration you no longer hear from the individual, he outright stopped answering, its now sunday so what happened with all the fake "pressure" he was blabbing about?

Hi Nicola. We are very sorry to hear about the experience you've had with this opportunity. We have spoken with the project team, who have since followed up with you directly and are still confirming final details with the client. We are reviewing this interaction internally to ensure better communication moving forward.
For any additional queries, please reach out to us at networkmembersupport@glgroup.com.

Struggle with GLG not respecting the advisor time. I have been booked for over 10 engagements over the last year or so. I have been paid for 7. The other 3 were booked and client was 1) a no show 2) cancelled AFTER the scheduled start time and 3) one arrived 20 minutes late. They REFUSE to pay you for your time which is not OK. If you book an hour and arrive 20 minutes late- common courtesy. Just a lack of respect for your time which is not OK.

Never paid
Never paid. The payment vendor they use "myprepaidcenter" does not work. I was supposed to be paid hundreds but I cannot access my money. Its been 3 weeks since my consultation and I have no received any payment that I can actually use.

Waste of time
Waste of time! Ive been qualified for so many projects. I complete the survey and provide my availability and have NEVER been contacted. It's been over a year and at this point I'm looking to have my info removed from their database as I get at least 2 emails a week about being "a fit" for their client. Total BS

Support to get started
I want to say Avery has been a big help with getting me set up and started. Always very prompt in responding and willing to help. This is my first experience with consulting, and I look forward to this process in my career.

Excellent expert network
I like GLG a lot and have found it useful as I grow my consulting practice. The only feedback I would give is it would be helpful to have a bit more predictability in the projects for my own planning purposes. Generally the projects are immediate and urgent. I also would love to engage in more long-term projects if that is a possibility.

Third graded service
Third graded service, Their both positive consultation and payment are useless. I had a survey with them ( survey no. 616681 ) recently. As per their site they have paid on 19th February. However till today no intimation to my bank. Even these scammers are not able to share the swift copy
