Briefly

    near -> nearly

    well familiar - delete the 'well'

    Since last 3 years -> For the last three years.

    I work as manager -> I work as a manager *or* I am a manager *or* I have worked as a manager.

    What are things -> What are the things
Beyond that there's some minor style issues. The misuse of 'since' is common among German and Dutch speakers so that would be my guess of your native language. I don't think any if this is a blocker for a director position but get yourself a good partner / secretary.

"Well familiar" isn't too strange a construct, though removing the well does certainly improve things here.

"quite familiar" seems more natural to me. Also, the odd comma spacing immediately jumps out at me.

Certainly "quite familiar" is more common.
