The Danger Zone: Top Reasons Candidates Fail

Based on our database of Handshake interview outcomes, avoid these common traps:

Leaving convoluted logic or unclear variable names.
Not systematically isolating the problem by checking caching, database queries, and serialization.
Lack of a clear strategy for skill normalization and deduplication.
Inefficiently calculating scores for all profiles without a way to quickly find the top K.

Test Yourself: Real Handshake Questions

Three real prompts pulled from our database.

Type · System Design

Design the backend for Handshake's 'Skills' feature, allowing users to add, verify, and display skills on their profiles. Consider how to handle skill normalization, potential duplicates, and how to integrate with external verification services.

Type · Code Clarity

Review the following code snippet which aims to match students to jobs based on skill overlap. Refactor it for clarity, efficiency, and robustness, adding comments where necessary.

Type · Algorithmic

Implement a function that takes a list of student profiles and a list of job requirements, and returns a list of all possible 'perfect matches' where a student possesses all skills required by a job and has at least 2 years of experience in each. Assume experience is stored as a map of skill to years.

Recruiter Screen

1
Type · Motivation
What interests you about Handshake's mission to connect talent with opportunity, and how does that align with your career goals as a software engineer?

Coding Screen

2
Type · Algorithmic
Given a list of student applications for internships, where each application has a timestamp and a list of skills, write a function to find the N most recent applications that contain a specific set of required skills. Consider efficiency for large datasets.
3
Type · Algorithmic
Implement a function to determine if a given set of job postings can be matched to a list of student profiles, where a match occurs if a student has at least 70% of the skills required for a job. Each student and job has a list of skills.

4
Type · System Design
Design a real-time notification system for Handshake that alerts students about new job postings matching their profile and alerts employers about new applications. Consider scalability to millions of users and jobs.
5
Type · System Design
Design the backend for Handshake's 'Skills' feature, allowing users to add, verify, and display skills on their profiles. Consider how to handle skill normalization, potential duplicates, and how to integrate with external verification services.

Onsite Coding

6
Type · Algorithmic
You are given a stream of job application events (e.g., 'applied', 'viewed', 'rejected') with user IDs and job IDs. Implement a function to calculate, for each job, the conversion rate from 'viewed' to 'applied' within a rolling 24-hour window. Handle potential data skew and late-arriving events.
7
Type · Debugging
A critical API endpoint for fetching student profiles is intermittently returning incorrect data, sometimes showing profiles of other users. The logs show no explicit errors, but there are spikes in latency. Debug this issue.

Behavioral / Leadership

8
Type · Ownership
Tell me about a time you encountered a significant technical challenge or bug in a production system that was not directly assigned to you. What steps did you take to address it, and what was the outcome?
9
Type · Influence
Describe a situation where you had a strong technical opinion that differed from your team or lead. How did you communicate your perspective, and what was the process for reaching a decision?
