What Is the Lyft Interview Process for Software Developers?

You need to understand the Lyft interview process to prepare well for Lyft interview questions. Lyft interviews are typically divided into four stages: recruiter screening, technical phone screening, On-site, and team matching.

Round 1: Screening with Recruiters

The recruiter phone screen is quite simple, consisting mainly of questions based on your resume and suitability for the software engineer post. Then, the recruiter will guide you through the interview process at Lyft. It is a 30-minute conversation.

Round 2: Technical Phone Screen 

In a technical phone interview, you need to spend one-hour answering technical questions with a Lyft software engineer. The questions on the technical phone screen are often less in-depth. However, they will cover any of the categories of questions discussed in the following section.

Round 3: On-site Interview

The Lyft software engineer On-site interview comprises four rounds:

  • System Design Interview - You can either use a whiteboard or a laptop for these questions. It would help if you clarified with your recruiter beforehand. This is a 60-minute interview.
  • Coding Interview - Interview for Computer Science fundamentals, including problem-solving, data structure, and algorithms. There are two coding rounds. 
  • Laptop Assignment - This assignment simulates the type of work you would do at Lyft day-in and day-out. You will have 90 minutes for this assessment.
  • Behavioral Interview - This comprises behavioral and situational questions concerning your previous work experiences, which helps an interviewer predict your future behavior.

Round 4: Matching Teams

After completing the On-site interview, you will be matched with possible teams and have exploratory calls with the managers on those teams. These future meetings will be more like chats than interviews, where you may get to know the team. This round simulates the working environment and helps determine the mutual fit for the role. 

Lyft System Design Interview Questions and Answers

Lyft system design interview questions include API, databases, and more. Lyft SQL interview questions form a major portion of these interviews. In a 60-minute interview, the hiring manager at Lyft asks you to design a large system relevant to Lyft's operations. 

You can use Google Draw as it allows you to collaborate in real-time to create, edit, and share drawings online. The interviewers can view your work, and you can also chat with them to explain your concepts. This process involves developing a way to communicate your strategies, proposing an API, and modeling database tables.

You will be given two system design questions. Through these Lyft interview questions, the hiring manager checks:

  • If your structure takes a systematic approach
  • Does your approach cover all requirements?
  • The feasibility, i.e., whether your answer is practical and could be implemented

Some common Lyft interview questions on System Design include:

Q1. Design a cab-hailing system from scratch

This Lyft interview question is very open-ended. Cab-hailing apps can have any number of features. You ought to distill the question down to 2-3 core features. Then design a system around those first. You can add more features later. The primary features can be:

  • User (Rider) and Driver Profile
  • The rider can hail a ride. A rider can find a nearby driver, and the driver can give a ride.

To prepare for System Design Lyft interview questions, practice and watch system design mock interviews. It would be best if you got familiar with Google Draw before the interview. 

Q2. How would you build a tourist-friendly bicycle rental app?

This Lyft interview question aims at analyzing your understanding of the primary requirements of a tourist-friendly app design. The following features can be incorporated into a tourist-friendly bicycle rental app.

  • Create a multilingual app that prompts the user to choose a language after installation.
  • Every bike will be fitted with a GPS device, and the bikes will be displayed to the user in a map view.
  • Payment in advance - Set up a payment wallet, a credit card, or a debit card.
  • Activate the bicycle - Scan the QR code to unlock the bike, start the trip automatically and record and display the rider's time.
  • Safety - Each bike will have a helmet affixed to it.
  • Parking spaces will be displayed to app users to guarantee that bikes are parked in densely populated city sections.

Q3. Design a dashboard as Lyft's product manager to monitor the app's health.

Software engineers have to primarily deal with Lyft application and structure. This Lyft interview question is commonly asked in Lyft system design interview rounds. The dashboard will include the following:

Buyer Side: 

  • Number of new downloads
  • Number of new first users
  • Number of total active users
  • Total distance driven
  • Funding

Driver Side:

  • Number of new drivers onboarded
  • Number of active drivers churn
  • Distance driven per active driver
  • Number of rides per active driver

Product-Related:

  • Number of customer support calls/tickets
  • Number of location sharing or safety feature usage rides
  • Number of active drivers per MAU active user
  • Number of app crashes 

Q4. Create Lyft for deaf drivers.

Consider the following to answer this Lyft interview question:

  • Drivers can text passengers before arrival, indicating their impairment and asking for their patience.
  • If users wish to be dropped off somewhere different, they can send quick, personalized messages requesting that the driver drop them off somewhere else. 
  • When the driver's phone receives a message from a passenger, it will vibrate, and the screen will blink for a few seconds to grab the driver's attention.
  • Passengers can spot the car using a brightly colored blinker and the license plate number.
