Preparing for the Phone Screen, Part 1
It has been a while since I last blogged here! Let's put that aside for a bit, though, in favor of a general-interest topic.
Nowadays I am happily working at VMware. I will probably be doing interviews and phone screens from time to time, and if you are being considered for a position in my team, I will be the "Perl Person" you have to speak with. If you are doing a little research ahead of time, I have a treat for you, because here are some of the questions I am going to ask. If I have space and/or energy, I will eventually post all the questions I will ask, but that will have to wait for later.
These questions aren't too complicated, but I don't necessarily expect you to get them all correct. In fact, you can get a number of them incorrect as long as, during the process, you convince me that you know which ones you don't know, and you know how to find the answer quickly.
- When have you used Perl? What version(s)? What platform(s)?
- What Perl book(s) have you read? What class(es) have you taken? Have you taught yourself? How much? What about?
- What is strict? What is warnings?
- Name a special variable. One other than $_. What is $_?
- What is perldoc?
- What is a Perl module?
- What is the difference between print and printf?
- What does local mean? Where could you use it?
- How do you open a file? What is the return value from open? What is $!?
- What is "null" in Perl? How do you tell if something is "null"?
- How do you find the size of an array?
- How do you write an infinite loop?
- What is a regular expression that matches any character?
- How do you remove a key-value pair from a hash?
- What is a "pointer" in Perl? What kinds are there? How do you make one? What can you do with them?
