Maybe a pre-screen challenge
Recruiter gets back to you.
Prepares you for the upcoming rounds
Schedules future rounds

18.
Step 3: Phone Screens & Technical Interviews
zero to one internship
I speak only for software engineering roles
Topics include:
• recall questions
• cs fundamentals
• algorithms
• operating systems
• networks
• technical discussions
• coding (whiteboard or collaborative editor)
• problem solving
• runtime analysis
• system design

19.
Step 3: Phone Screens & Technical Interviews
zero to one internship
•Several rounds
•phone screens
•technical interviews
•Increasing level of difficulty
•Usually progresses from non-coding to coding.
•Varies most here: Interns vs. full-time
•might have fewer rounds for interns - woot!
•might require onsites for full-time

Some thoughts on technical
interviews
something you’ll probably have to do
eventually

22.
What happens
technical interviews
•45 minutes - 1 hour
•Outline
•Intro, soft questions
•Actual question (usually only one)
•Possibly another question
•Q&A (You ask the questions)
•Might be in person, with a whiteboard, or over the phone, with a
collaborative editor (coderpad, google docs, etc).

23.
Sample soft questions (Behavioral)
technical interviews
•Tell me a project that you've worked on that's technically
challenging and walk me through your problems and how you
solved them.
•Tell me about yourself
•Tell me about [X]
•[X] is something on your Resume

24.
Sample soft questions (Culture fit)
technical interviews
•Do you use our product? What do you love about it and why?
•Why do you want to join [the company]?

25.
Sample technical questions (short, recall)
technical interviews
•What is 0x05 + 0x1a
•What is a deadlock?
•What is“this”? (JavaScript)
•What is the runtime of various operations of a hashtable?
•What’s the difference between a process and a thread?

26.
Sample technical questions (non-coding)
technical interviews
•Explain to me what happens when I type“google.com”into the
address bar.
•Design bit.ly

27.
Sample technical questions (coding)
technical interviews
•Find an element in a sorted, pivoted array.
•[1,2,3,4,5] => [4,5,1,2,3]
•How many ways are there to buy a given amount of coke if they
come in the following sizes: 1, 6, 24?
•eg. 7 => [1,1,1,1,1,1,1], [1,6] => 2 ways.
•Implement a stack with an additional #min method that returns the
min element in constant time.

28.
Sample technical questions (coding, rare!)
technical interviews
•Design and build a simple application in framework X
•Programming language specific questions (how do you do X in
language Y?)

29.
Me: Before the interview.
technical interviews
•Practice practice practice
•Don’t cheat. It won’t work.
•Be fresh and ready for the interview
•Don’t underestimate a phone screen.
•logically: you’re expected to bring your best self for the
interview..
•Practice soft questions as well
•Don’t sweat this.
•But often underestimated.
•Don’t want to get off on a bad start.
•Think of questions to ask the interviewer
•Some people have pet questions they like to ask every time.

30.
Me: Before the interview.
technical interviews
•Topcoder, leetcode, hackerrank
•Read: cracking the coding interview
•WRITE CODE ON PAPER.

31.
At a high level
technical interviews
The interview is meant to be a conversation to access:
•Whether you can fit in as a“peer”
•taking part in technical discussions
•able to“converse”on the same level
•How you measure up against other candidates
•are you good (enough)
•Whether you are someone they’d want to work with

32.
Me: during
technical interviews
•Think before you speak
•Its okay to take a few seconds to think.
•jumping to conclusions is pretty bad/unrecoverable.
•Clarify any doubts
•Communication skills.
•You can always ask them to repeat stuff, or for examples, input/
output (when given questions)
•Articulate your thoughts clearly
•this is super important.
•esp. if not in person
•explain what you are thinking, every step of the way.

33.
write a function that removes
duplicates from a list

34.
Me: during
technical interviews
•OCD, code should compile.
•Don’t be sloppy with semi-colons, braces, indentation, syntax (its
not that hard)
•write pseudocode first, replace with real code as you go along
•test proactively
•after completion, run your code.
•“I’m going to step through my code now to make sure I don’t
make any obvious errors”
•test meticulously
•List testcases on the board.
•Step through every line, every variable assignment.
