Seriously, these guys are offering a service you desperately need. Get over the fact they're not as tech-savvy as you; they possibly have the connections you need.

People skills, people.

Wait a moment, nowhere did he say "these morons couldn't open an ODT file".

I always send my CV in PDF format.

So do I, but a lot of agencies insist on Word format, because it's easier for them to hide your contact details when they send the CV to their clients.

I used to do this, until about the third time I was asked to just send a .doc

Some automated HR systems can parse out a Word document but can't do anything with a PDF.

But why would anyone send a CV in a text format until and unless specifically asked, which usually happens when the HR needs to edit the file to convert it to some company wide practised format, for reasons known by them or above almighty.

Everyone sends the PDF.
