Salary progression for me

First job (India) 2006 - ~$4,000 per year

Second Job (India) 2008 - ~$10,000 per year

Third job (US) 2010 - $105k

Fourth Job (US) 2012 - >$150K

Things have gone well since then too. The main thing that has kept things going up so far is really practicing before interviews to try and get better and never shying from looking for better opportunities. The company and I have a transactional relationship, not an emotional one.
