writing a brief description of yourself I have just started my first job in a company as an engineer, I was asked to write a brief description of myself which will be sent to all the staffs. 
Could you please provide some template? how we can write an interesting autobiography?

edited: Having said that some humor or random facts can be included in this bio.
I would recommend asking whoever is asking you to do this for a past example. Different institutions have vastly different styles -- e.g. some places might be OK with including some humor or random facts in your bio, whereas other places are all business.

That said, you can always get some generic examples by googling "bio examples".

(Also, since this is a workplace question, it's probably more appropriate for https://workplace.stackexchange.com.)
