Yale Computer Science Technical Interview Preparation Guide

What is the Technical Interview?

Recruitment for Computer Science internships involves a series of technical interviews. While all technical interviews are designed to gauge ability with coding, there are different forms:

Coding Assessment: a time-limited test given through online coding platforms used to assess your ability to quickly and efficiently write code.

Technical Screen: which is a live interview in which a student walks their interviewer through their thought process while writing code. In the technical screen, code can be written on a coding platform or on a white board, so it is best to practice in both settings.

When does the Application Process Begin?

Most internships start recruitment early. Applications can be due by mid summer or early fall, especially at large tech companies; some are evaluated on a rolling basis, so applying early is key. However, startups typically recruit during spring, or Feb-May.

Many internships are intended for students with more advanced coding experience (CS223 or higher), but some companies also offer internships geared towards students earlier on in their CS education (e.g. Facebook University, Google Step, Explore Microsoft).

Where do Computer Science Opportunities Exist?

Common sources of Computer Science internships include large tech companies and startups, sometimes through Venture Capital firms, but almost every company has some Computer Science-focused internship offering.

Receiving referrals from upperclassmen can greatly increase the odds of being offered an interview.

The top 5 employers of Yale Computer Science students include: Google, Facebook, Microsoft, Apple, and MongoDB

Internship postings can be found on LinkedIn, Indeed, AngelList and the jobs tab and Resources > CareerShift in Yale Career Link.

Common Intern Job Titles: software engineer, product management, data science, front-end engineer, back-end engineer, and full-stack engineer.
