He's like the network lead.

So back then, Tim Hawkins is working at the other side of Google, like the bigger side of Google.

And one of his first projects was a little tool that you would put on the motherboard.

It had about nine lights on it.

And the lights would flash back and forth and it would tell you what DIMM slots were potentially bad.

The technicians that were fast, they didn't waste time like running a program to do an extensive test of the memory.

You learn how to use this little tool

device and you would walk up to the motherboard so the thing i would do is like before i do anything put this on the motherboard get the reading and i learned to trust it over time dim one dim two are bad and the goal would be all right i have all this memory on my cart you squash those two dim slots make sure that that's done first reboot the machine and you might be like i think that's the only thing wrong and again you were put in the system i believe i only need to do dim one and two

And the way you were measured is how long before that machine gets kicked back to repair.

So if it doesn't get kicked back within, I don't know, 30, 60 days, you did a good job.

If you didn't, your scores would be low.

So for the technicians that were just reckless, right, they wouldn't even try.

You're just swapping the wrong part.

You're swapping the wrong hard drive.

And so your stuff is always coming back for repair.

You were not efficient.

So I got to the point where I can maintain high 90s, but also repair, let's call it three times more machines than other people.

So lots of machines, greater return.

And then I learned how to do the network switches.

And then there's power audits where you're lifting up tiles from the floor.
