First, I use a Mac :) Then I use Visual Studio Code (with a bunch of extensions) as my IDE for all development, and exclusively use the Google Chrome developer tools for all client-side stuff. For one-off huge files/logs, I use Sublime. For design I use Sketch. I also use iTerm as my terminal replacement, and can't live without the zsh shell. For general computer productivity, I use Alfred for searching through files/apps, and Better Snap Tool to give me window snapping capabilities. Oh, and Bartender is really great for hiding all the status bar icons. :D

Aw, these are great questions! I've also never interacted with Peter Theil, but Dan, our CEO, is a super great guy and he takes time out of his busy day to talk with recent college grad nobodies like me :) My favorite things: the culture and the innovation lab. The culture because you can work from home whenever you feel like it, take long lunches if you've had a rough day, or work in the lounge. As long as you get your stuff done on time and your code is up to snuff, you can do whatever you need to do to recharge and keep your mind sharp. The innovation lab is also amazing. It's all about out-of-the-box thinking and daring to dream bigger and crazier ideas... and it's full of nerds who are learning everything from cryptocurrencies to VR. And the lab really expands your mind and they host great hackathons and events.

For me, I'm head-over-heels in love with JavaScript and all that it stands for. Since PayPal really made an effort to push forward the adoption of Node.js, we have a lot of solid full-stack engineers that can write it back to front. I think one recurring challenge we have though is migrating our legacy systems over from Java/C/C++ over to JavaScript and Node; we have to do a lot of work to ensure that legacy migrations go smoothly and without a hitch.
