My experience with endorsements tells they can be not only deceiving, but also a trap.<p>There's this guy which I used to work with that was not very good in the job and used to distract others at work very often, not being really productive most of the time - but he was generally nice to everyone, so nobody really disliked him.<p>He ended up leaving the company, and was hired by another company which we had business with. After some time, his new employer called our boss to tell he left, taking with him all the code of the project he was and starting a company by himself with this code.<p>This may seem bad already, but it was not the end: a few years later, the guy comes back asking me for recommendations on LinkedIn - when I checked his profile, I found he got a lot of code from the first company as well - where we used to work together - and put on his Github, with copyright headers stating he was the author. In fact, he did that with code <i>I personally wrote</i>.<p>Of course, I didn't endorse him - but if I go to his LinkedIn page today, there are tons of recommendations by ex-colleagues, including recommendations for things that he barely worked with.<p>And this is just one example. Most co-workers I have or had that were really good in what they do have zero to a few recommendations, and usually in very specific stuff that don't every start to cover their knowledge.<p>So, my advice is: if you use LinkedIn recommendations to anything serious, you are doing something wrong.
