Hello Umair,
In addition to the steps I described above I then used the Internet to identify all of the investment managers that I could. I eventually created a database of over 2,000 money managers. I then sent over 500+ of them my CV and a cover letter. Of the 500 I sent out I got 50 responses, 40 "nos" and 10 interviews. Of the interviews I received 3 job offers.
If you have personal contacts in the business - which I did not - then I would start with them first.
With smiles,
Jason
