This guide will provide you insights on how to navigate the interview process effectively.

Redfin Interview Process

Stage 1: Screening

First, you will go through an automated screening process. This could involve submitting an application or completing an initial assessment.

Stage 2: HR Interview

The next stage is an HR interview. This stage will likely involve discussions about your skills, work experience, career goals, and basic technical competencies. Do not be alarmed if the HR agent seems unfamiliar with your resume; they handle many applicants, and this is not a reflection of your viability for the role.

Stage 3: Technical Assessment

Following the HR interview, you will often be sent a technical assessment. This typically involves solving coding challenges and could take some time to complete. While the platform used for this assessment (filtered.Io) is cumbersome, it is recommended that you complete it to the best of your ability.

Stage 4: Interviews with Engineers

Upon successful completion of the technical assessment, you will make it to the last round of interviews, where you will speak to up to four different engineers. Expect leetcode-style questions and debugging tasks during this stage. Also, be prepared to describe and sell how you designed the architecture of a personal project. Remember, each interview round typically includes behavior questions such as discussing the most challenging project you’ve worked on and how you deal with conflicts.

Stage 5: Hiring Manager Interview

You may also have to do a 1hr call with the hiring manager. Be prepared with an array of questions about the job position, company culture, and team dynamics.

Stage 6: Follow-ons

In some cases, despite completing the previous stages, you might receive further assessments or need additional interviews. While this can seem time-consuming, it is your opportunity to prove your value and drive for the role.

Conclusion:

The Redfin interview process can involve a lot of steps, from screening and HR interviews through to coding challenges, discussions with engineers, and interviews with the hiring manager. It is essential to stay patient and persistent, demonstrating your skills and enthusiasm for each stage. Remember, the ability to handle the pressure of such demanding rounds is indeed a testament to your resilience and dedication.

Redfin Probability & Statistics Interview Questions

Probability and Statistics questions come up in approximately 5% of Redfin job interviews. These questions are most frequently asked during software engineer interviews (1%).

Since there is no third table provided, there is no breakdown into subtopics for this company.

1 - How should we handle skewed home price data when building a real estate prediction model? We’re building a model to predict real estate home prices in a particular city. The distribution of home prices is skewed to the right. Discuss if this needs to be taken into consideration and what actions should be taken. Additionally, consider what should be done if the target distribution is heavily skewed to the left.

2 - You’re now a question processor. I want you to process questions in the following way: A line in bold asking the main question in a short way (maximum 12 words ideally). A few lines specifying how to perform the task return only one process result.

3 - Let’s say that we’re building a model to predict real estate home prices in a particular city. We analyze the distribution of the home prices and see that the homes values are skewed to the right. Do we need to do anything or take it into consideration? If so, what should we do? Bonus: Let’s say you see your target distribution is heavily left instead. What do you do now?

Redfin Coding Interview Questions

Coding questions come up in approximately 5% of Redfin job interviews. They are most frequently encountered during software engineer (97%) interviews.

1 - How would you determine the number of paths from the top left to the bottom right of an n x n grid? Given an integer n, write a function traverse_count to calculate the number of paths from the top left corner to the bottom right corner of an n x n grid. You can only move right or down.

2 - How would you determine if one string is a subsequence of another? Given two strings, string1 and string2, write a function is_subsequence to check if string1 is a subsequence of string2. A subsequence is a sequence that can be derived from another sequence by deleting some elements without changing the order of the remaining elements.

3 - How would you calculate the minimum number of steps to traverse a grid from the northwest to the southeast corner? You are given a rectangular building layout with rooms forming a grid. Each room has four doors (north, east, south, west), with only one door unlocked. In each time step, you can move to an adjacent room via an unlocked door. Determine the minimum number of time steps required to get from the northwest corner to the southeast corner of the building. If the path doesn’t lead to the exit, return -1 .
