Recently I’ve been interviewed by Google, three times, by phone, in what seems like an interviewing spree. The first two times I did so-so in my interviews. The third time I did extremely well. Nevertheless I was rejected for the position, which led me to think they aren’t actually intending to hire right now. They’re perhaps building a database of possible system administrators and software engineers to hire eventually.

But why would they be doing that? Google isn’t a recruiting company. Why would they devote resources to create such a database? I wondered for awhile, and then it struck me. Google is planning something big that will require a lot of technical talent, in a rush. There’s only so many things that Google could be wanting to do, and the one that sounds more plausible seems to be: building a giant worldwide mobile ISP. They’re aiming at the mobile phone companies with an Internet based offer, perhaps using WiMAX or a similar technology.

They’ve recently released Android 2.3 with integrated support for VoIP (SIP). I’m using it on a daily basis and it works very well. Their mobile operating system have surpassed the iPhone in the US. Google bought Gizmo5 last year and is offering their own Google Voice services. Google is planning to snatch the worldwide voice network off the hands of the incumbent telephone and mobile phone companies. These haven’t been innovating quickly enough on mobile services, since their main revenue stream comes from people paying voice minutes and SMS.

Google needs faster bandwidth for mobile devices, to deliver their content and drive advertisement revenue from that platforms. Google need people accessing the Internet more often, everywhere. They’ll benefit from people using the Internet for their voice communications, instead of the old phone network. Google wants to make history. They’re the ones who’ll finally dethrone the plain old telephone service for both fixed and mobile voice communications, even more spectacularly than the email did with the written letter.

Mobile and fixed telephone operators: thunderstorm approaching.
