I was an engineer at a design services firm. My 'boss' was 500 miles away, along with the rest of my team. People threw bugs and tasks at me and I did them. At my company, I'd walk in, go straight to my cube, and sit there all day. Occasionally I'd get social. Even when I was assigned to other projects working with local teams, or even leading teams of people, I managed to make it work. People just got used to me being that way I guess.

I wasn't really hiding it. I have long hair(usually worn down) and had a reputation as being a party guy. But I had an outstanding technical reputation and that shielded me from scrutiny. I was making my company a lot of money and as long as that continued I don't think anyone really gave a shit.

How do you think being high affected your work?

I usually did the minimum required of me. While I did challenge myself and learn new things, I stuck to the easy stuff. I worked the minimum amount of time every week and shied away from taking on voluntary projects which would have made my usefulness to my employer more obvious. I got my job done in 20-30 hours, billed for 40, and went home(shitty, I know).

When times got tough for my client(after nearly 6 years) I was eventually replaced with a WiPro guy.

I could have learned C++14, but instead I stuck with what I knew. I could have learned algorithms, but I stuck with the driver/systems/embedded stuff I knew. I could have learned the security frameworks and been really valuable right now.

The last 2 years have been a time of furious catching up. I'm now being courted by FANG companies and hoping I can make the cut(I need to bump my salary to afford alimony... long story).

As long as you a) have experience being stoned in public, and b) don't smell like burnt flower, it's not too difficult to fly under the radar. Just try not to talk with people, however if you do, I've learned that overloading a person's mind distracts them enough to not pay attention to your slightly glassy eyes. Basically: do your job and ask them to do theirs.
