# Read from the file words.txt and output the word frequency list to stdout.

cat words.txt | tr  -s ' ' '\n'  | sort | uniq -c | sort  -r| awk '{print $2, $1}'


#tr -s: truncate the string with target string, but only remaining one instance (e.g. multiple whitespaces)

#sort: To make the same string successive so that uniq could count the same string fully and correctly.

#uniq -c: uniq is used to filter out the repeated lines which are successive, -c means counting

What to Expect and Tips

• 45-minute systems interview, focus on responding to real world problems with an unhealthy service, such as a web server or database. The interview will start off at a high level troubleshooting a likely scenario, dig deeper to find the cause and some possible solutions for it. The goal is to probe your knowledge of systems at scale and under load, so keep in mind the challenges of the Facebook environment.
• Focus on things such as tooling, memory management and unix process lifecycle.

Systems

More specifically, linux troubleshooting and debugging. Understanding things like memory, io, cpu, shell, memory etc. would be pretty helpful. Knowing how to actually write a unix shell would also be a good idea. What tools might you use to debug something?

Interview is all about taking an ambiguous question of how you might build a system and letting
