I had a terrible experience with climber.com, I think it is important for people to know which agency is really helpful with career development, which is not. Here is what I have experienced with climber.com:
1. In February, I purchased the membership of climber.com. After that, I always received the email from CEO about the service of resume and cover letter (here and after I will demonstrate how they want you spent money); after I purchased the service of resume and cover letter, immediately I received a phone call ask my credit card information, and told me how much effort they will put in to make the resume look good; also, they told me 6 months of membership could be waived as a discount; the service is around 650$. The result is quite disappointing, they ask me to write a draft of my resume and fill in the forms; note here, you need to do the work all yourself; what they do is only put a frame on your resume and combine all the information you fill in the form! The language is ridiculous, I'm a research scientist with Ph. D., but the languages they use make me look like a person with high school education level. I have to delete it and edit myself again. I asked for the refund or half refund, but didn't work.
2. As talked when I purchased the service, 6 months membership fee was supposed to be waived, but that's not the case, every month my credit card will be billed 39.99$ until this August, when I found the fact, so I cancel the membership.
3. I called them several times, they just keep transferring my call, and finally I can reach a person who said they will mail me the check on 9/5, I told them my updated address, but haven't received anything until now 10/5. I called them 5 times again, no one picked up the phone; I left three messages, no reply at all. This is an obvious contrast with their enthusiasm before I purchased the service (see point 1).
The conclusion is DON'T use climber.com, not helpful at all and you will waste your money. I personally think they will close business soon because no one will refer to their friends with such poor service and reputation.
