Submitting Your Application

The first step is to submit a compelling application that reflects your technical skills and interest in joining Addepar as a Software Engineer. Whether you were contacted by an Addepar recruiter or have taken the initiative yourself, carefully review the job description and tailor your CV according to the prerequisites.

Tailoring your CV may include identifying specific keywords that the hiring manager might use to filter resumes and crafting a targeted cover letter. Furthermore, don’t forget to highlight relevant skills and mention your work experiences.

HR Recruiting Call

Once your CV is shortlisted, a recruiter from Addepar's Talent Acquisition Team will make contact to verify key details such as your experiences and skill level. Standard questions like "Who are you?" and "What are you looking for?" will be asked. This is primarily a screening call to ensure alignment with the company’s values and minimum requirements for the role.

This call typically takes about 30 minutes.

Technical Screen

If you pass the HR screening, the next step is a technical screen conducted over Zoom with an engineer. During this 1-hour session, you will encounter a coding question. This round aims to test your problem-solving skills and technical knowledge.

Be prepared for questions on designing systems like a key/value store or other problem statements such as:

• Design a key/value store that supports transactions.
• Write a file sorting system in any language.
• Merge N files which consist of new-line delineated text into a sorted output file.

Take-Home Assignment

In some scenarios, you may be given a take-home assignment. Addepar sometimes sends a project with a specific challenge that aligns closely with the job description. You may be given about 3 hours to complete it. Example assignments might include:

• Build a page that shows data from a 3rd party API.
• Create a portfolio reconciliation program to output any anomalies in a given closing portfolio given an opening portfolio and a series of transactions.

Onsite Interview Rounds

If you successfully clear the take-home assignment, you will be invited for onsite interviews. This typically involves multiple 1:1 rounds with different engineers. The onsite interview includes:

• A product demo: introducing what Addepar does and its key technologies.
• Technical rounds: these may involve coding on a laptop or whiteboard, system design problems, data structure design exercises, and debugging tasks.

Interview problems might include: - Implement a function that provides the longest incrementing path in a 2D array. - Solve a regular expression matching problem from LeetCode. - Debug an issue in a Python HTTP client.

Quick Tips For Addepar Software Engineer Interviews

• Understand Addepar’s Domain: Since Addepar works extensively with financial data, having a background or understanding of financial systems can be a significant advantage. Make sure you know key concepts related to their domain.
• Prepare for Coding Challenges: Most software engineer interviews will include algorithm and system design questions. Practice on platforms like Interview Query to hone your problem-solving skills.
• Communicate Clearly: Interviewers at Addepar value clear and logical problem-solving processes. Make sure to verbalize your thought process and approach to solving a given problem.

Typically, interviews at Addepar vary by role and team, but commonly Software Engineer interviews follow a fairly standardized process across these question topics.

• Write a SQL query to select the 2nd highest salary in the engineering department. Write a SQL query to select the 2nd highest salary in the engineering department. If more than one person shares the highest salary, the query should select the next highest salary.

• Write a function to merge two sorted lists into one sorted list. Given two sorted lists, write a function to merge them into one sorted list. Bonus: What's the time complexity?

• Create a function missing_number to find the missing number in an array. You have an array of integers, nums of length n spanning 0 to n with one missing. Write a function missing_number that returns the missing number in the array. Complexity of (O(n)) required.

• Develop a function precision_recall to calculate precision and recall metrics from a 2-D matrix. Given a 2-D matrix P of predicted values and actual values, write a function precision_recall to calculate precision and recall metrics. Return the ordered pair (precision, recall).

• Write a function to search for a target value in a rotated sorted array. Suppose an array sorted in ascending order is rotated at some pivot unknown to you beforehand. You are given a target value to search. If the value is in the array, then return its index; otherwise, return -1. Bonus: Your algorithm's runtime complexity should be in the order of (O(\log n)).

• Is this a fair coin? You flip a coin 10 times, and it comes up tails 8 times and heads twice. Determine if the coin is fair based on this outcome.

• Write a function to calculate sample variance from a list of integers. Create a function that takes a list of integers and returns the sample variance, rounded to 2 decimal places. Example input: test_list = [6, 7, 3, 9, 10, 15]. Example output: get_variance(test_list) -> 13.89.

• Is there anything suspicious about the A/B test results with 20 variants? Your manager ran an A/B test with 20 different variants and found one significant result. Evaluate if there is anything suspicious about these results.

• How to find the median in a list with more than 50% of the same integer in O(1) time and space? Given a sorted list of integers where more than 50% of the list is the same repeating integer, write a function to return the median value in (O(1)) computational time and space. Example input: li = [1,2,2]. Example output: median(li) -> 2.

• What are the drawbacks and formatting changes needed for messy student test score data? You have student test scores in two different layouts (dataset 1 and dataset 2). Identify the drawbacks of these layouts, suggest formatting changes to make the data more useful for analysis, and describe common problems seen in messy datasets.

• Would you think there was anything fishy about the results of an A/B test with 20 variants? Your manager ran an A/B test with 20 different variants and found one significant result. Would you suspect any issues with these results?

• How would you set up an A/B test to optimize button color and position for higher click-through rates? A team wants to A/B test changes in a sign-up funnel, such as changing a button from red to blue and/or moving it from the top to the bottom of the page. How would you design this test?

• What would you do if friend requests on Facebook are down 10%? A product manager at Facebook reports a 10% decrease in friend requests. What steps would you take to address this issue?

• Why would the number of job applicants decrease while job postings remain the same? You observe that the number of job postings per day has remained constant, but the number of applicants has been decreasing. What could be causing this trend?

• What are the drawbacks of the given student test score datasets, and how would you reformat them for better analysis? You have data on student test scores in two different layouts. What are the drawbacks of these formats, and what changes would you make to improve their usefulness for analysis? Additionally, describe common problems in "messy" datasets.
