Fresh Electrical engineer graduate offered to work as a bid manager? pros and cons? Please share with me your opinion on how to proceed?

As you are fresh graduate its important for you to get experience. At this stage do not look for pros and cons. At the moment getting experience has more weight-age then looking into pros and cons. Once you are in the market you will be able to find job relevant to your expertise. So go for it, do not lose opportunity.

Individual is best judge for himself interest, to give good answer its necessary to know many personal fact about you, please use you sense, I’m sure you will reach to final decision, with best wishes .

I'm very sorry, I am unable to provide you with an answer, however look at it in salary prospective.

I think earlier time to start as  a bid manager. Kindly read job description and try to test yourself whether you are able to to perform this role efficiently or not.  I would like to recommend you to find a relevant job to increase  your experience as an Electrical Engineer Graduate  for the Construction & Installation for the electrical equipment and then your experience will qualify you to achieve this job or other jobs efficiently. 

I would suggest reading the job description and making some online research about the role offered and see if you as a person is able to do the required tasks or not.

Fresh graduate can not be as a bid manager. Bid manager needs plenty of experieces to do risk management

Its more about individual key interest, Bid Management role is the most eye catching in organization as it involves business/finance. I had been in Bid Profile and it has open avenues for me to work in other domains as well, the kind of knowledge individual can cater from the scope of work can be asset for him. 

SO, I recommend early to start is worth.
