Applied to the position through a recruiter and an interview was scheduled.

It involved two phone interviews:

• One for coding
• The other for systems.

Coding questions were pretty standard and repeated.

Question 1:

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/s² (gravitational constant).

Write a program to read 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.

$ cat dataset1.csv NAME,LEG_LENGTH,DIET Hadrosaurus,1.4,herbivore Struthiomimus,0.72,omnivore Velociraptor,1.8,carnivore Triceratops,0.47,herbivore Euoplocephalus,2.6,herbivore Stegosaurus,1.50,herbivore Tyrannosaurus Rex,6.5,carnivore

$ cat dataset2.csv NAME,STRIDE_LENGTH,STANCE Euoplocephalus,1.97,quadrupedal Stegosaurus,1.70,quadrupedal Tyrannosaurus Rex,4.76,bipedal Hadrosaurus,1.3,bipedal Deinonychus,1.11,bipedal Struthiomimus,1.24,bipedal Velociraptorr,2.62,bipedal

1. Split an array such that their sums are the same.

Systems questions:

• Explain the vmstat command.
• System calls.
• Asked to write a program using bash.

Interviewers and recruiters were super awesome.
