Most don't like people visiting or calling and most don't even send a reply.
I didn't bother sending 40 plus cv's out. But each CV i sent had a covering letter which i put alot of effort into and my CV was doctored to what I thought the company was looking for. To be honest at the moment if you are low hours you will have to be very lucky to get a bite. 1000hrs plus Pilots are getting jobs. So stick in there the backlog of instructors will eventually run out and the hours required will decrease. ut the longer you stay in the <300 hours bracket the longer you will be leap frogged by graduating CPL's who go and instruct for a season to get there hours up.
