Refrigeration engineers, HVAC engineers, equipment engineers, which engineer employment environment treatment is good? Can refrigeration and HVAC engineers take the test together? Say detailed...

On your question, generally speaking, the key is to look at the nature of your current job! In my opinion, these public engineers are similar! Now belongs to the era of having a license! Generally have one of these certificates, the work will not be a problem, the key is to look at the direction of your future work, generally speaking, this is to look at the nature of the work associated with you sprinkle!

You are talking about the examination of engineers, not the evaluation of engineers, is the seniority did not reach?

Engineer this can be a lot of test, the key is your work experience can play perfect not to spread! Hehehehe 。。。。

Personal advice, if the conditions now allow you to take as many engineer certificates as you can, take as many as you can! Because according to the gossip we got, soon engineers will require only can test, can not evaluate! Heh heh heh 。。。。。
