I wonder if the infected squirrels will reinfect the growing rat population in San Francisco and repeat the cycle.
There is actually another questions "how much?". There is also no opposite for that.
I worked at a BigCorp and it was one of the worst years of my life. The work/life balance was awful, and the pay was shit compared to the hours I put in and satisfaction I got out of the job. All other experiences I've had have been much more satisfying.
On top of this, people think BigCorp is a safe bet where a startup is not, but BigCorp lays people off in large swaths all the time because their stock price moves a millimeter in some random direction.
I'm a developer with about 6 years experience in full stack web app development (Rails & Django mostly), and I recently got my ass absolutely kicked during a couple of live coding challenges that were very heavy on theory (also worth mentioning that I'm a self-taught dev without a CS degree).
I started talking to some former coworkers about my experience, and I got 2 main responses: A) it's imperative to have a CS foundation regardless of your degree if you want to advance in your career, and B) employers only consider prior experience to certain degree.
The two interviews that I bombed involved heavily contrived coding challenges that tested CS fundamentals in ways that I've never encountered in a professional environment, so it doesn't surprise me at all to see services like this popping up.
I was failing interviews too until I picked up an undergrad CS algorithms book and read through the first few chapters on data structures and theory. Then I signed up for LeetCode premium. After a couple months of reading and practicing, I was getting an offer from every place I interviewed at. Now I’m at one of those big name software companies, and if I’m ever asked to interview a candidate—well, I don’t know what I’ll do. Maybe something with a binary search tree. I’ve literally never had to use that in 8 years of development. :)
