Any call or email from a recruiter whos name I cannot pronounce goes straight into File 13.
I use a Google Voice number on my resume these days. Google translates each voicemail and sends me a text message with the contents of each message.
If the text message reads as total nonsense, I know Apu is calling & I ignore the call.
These days, Apu has been reduced into being a pimp for positions at TCS, Wipro, Infosys, HCL, etc...
