January 1, 2017

Positive ExperienceNo Offer

Process

The first interview was a 30-minute phone call.

After that, there was a 45-minute online test. You could choose whichever language you were comfortable with.

The interviewer was very helpful, offering indirect hints or questions when I was stuck.

Questions

You will be supplied with two data files in CSV format.

The first file contains statistics about various dinosaurs.

The second file contains additional data.

Given the following formula:

speed = ((STRIDE_LENGTH / LEG_LENGTH) - 1) * SQRT(LEG_LENGTH * g)

Where g = 9.8 m/s^2 (gravitational constant)

Write a program to read in the data files from disk. It must then print the names

of only the bipedal dinosaurs, from fastest to slowest. Do not print any other information.

The best job I've ever had

Production Engineer • Current Employee

Menlo Park, California, United States

Pros: They grill you hard in the interview, but once you're in, you get a lot of autonomy and freedom to make decisions about how you think things should be done. Zero bureaucracy or red tape, very few meetings, and people are encouraged to build what they think will work. Two of the common sayings there are "code wins arguments" and "what does the data say?" This means that if people disagree about something, the debate gets resolved by looking at numerical data and/or by building something and seeing whether or not it works. This is a very fast, turn-on-a-dime, high productivity, zero BS environment. It's also a lot of fun to work there. People work hard and play hard.

Cons: The cons at Facebook mostly fall under the heading of "growing pains". Technologically, things move so fast that the layers of the technology stack are often in flux. If you are building a system that depends on other systems at FB, be ready for them to change underneath you. Nothing stays the same for long at Facebook. Every layer of the stack changes, and changes quickly. At the human level, the company has also grown very quickly, which means many of the lower-level managers are new, inexperienced, or got promoted to management for being good with computers (but not necessarily with people). It can be frustrating to report to junior managers and/or people who are clueless about social skills. With that said, the higher-level, more senior managers tend to be really good, and their skill often "trickles down" in various ways.
