In an interview with RQP 104.3 FM, Megadeth mastermind Dave Mustaine explained how  he choose their new drummer for Megadeth. He also revealed his special secret about not sounding like Metallica. He said (transcriped by Blabbermouth):

It’s very difficult. The drumming is the hardest part in the band, because you need to be really physically fit every night — every night, no matter what. You can’t be sick. And I think that drumming is a thankless position.

A lot of times, the drummers go without being recognized for how hard their job is. Consequently, you get drummers that have bad attitudes after a while. It’s hard to be around them, because a lot of drummers don’t get the recognition they deserve, and they get bitter.

For us, we’ve been really lucky with the last two drummers we had — with Chris [Adler] and with Dirk [Verbeuren]. And even the guy before Chris, Shawn [Drover], was an easy-going kind of guy. But it’s not always like that. And Chris helped us find Dirk. Dirk is a lot like [late MEGADETH drummer] Gar Samuelson, which is really refreshing, because that’s how this whole thing started.

I was playing jazz-metal-type riffs, because I didn’t wanna sound like my last band [Metallica]. I wrote that shit, I can write whatever I want, so I knew what not to do, so I did something different, and that’s how Megadeth was born. I wanted to do something a little bit different, and I needed a different kind of drummer to do that.”
