Submitting Your Application

The first step is to submit a compelling application that reflects your technical skills and interest in joining Xanadu Realty as a Product Manager. Whether you were contacted by a Xanadu 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.

Recruiter/Hiring Manager Call Screening

If your CV gets shortlisted, a recruiter from the Xanadu Talent Acquisition Team will make contact and verify key details like your experiences and skill level. Behavioral questions may also be a part of the screening process.

In some cases, the Xanadu Product Manager hiring manager stays present during the screening round to answer your queries about the role and the company itself. They may also indulge in surface-level technical and behavioral discussions.

The whole recruiter call should take about 30 minutes.

Technical Virtual Interview

Successfully navigating the recruiter round will present you with an invitation for the technical screening round. Technical screening for the Xanadu Product Manager role is usually conducted through virtual means, including video conference and screen sharing. Questions in this 1-hour long interview stage may revolve around Xanadu’s quantum software projects, scientific Python ecosystem, and relevant technical skills like SQL or data analysis.

Depending on the seniority of the position, case studies and similar real-scenario problems may also be incorporated.

Onsite Interview Rounds

Followed by a second recruiter call outlining the next stage, you’ll be invited to attend the onsite interview loop. Multiple interview rounds, varying with the role, will be conducted during your day at the Xanadu office. Your technical prowess, including understanding of quantum software, scientific research methods, and project management capabilities, will be evaluated against the finalized candidates throughout these interviews.

If you were assigned take-home exercises, a presentation round may also await you during the onsite interview for the Product Manager role at Xanadu.

Typically, interviews at Xanadu Realty vary by role and team, but commonly Product Manager 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.

• Create 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 SQL query to select the top 3 departments with at least ten employees and rank them by the percentage of employees making over 100K. Given employees and departments tables, select the top 3 departments with at least ten employees and rank them according to the percentage of their employees making over 100K in salary.

• Develop a function traverse_count to determine the number of paths in an (n \times n) grid. Given an integer (n), write a function traverse_count to determine the number of paths from the top left corner of an (n \times n) grid to the bottom right. You may only move right or down.

• Create a function is_subsequence to check if one string is a subsequence of another. Given two strings, string1 and string2, write a function is_subsequence to find out if string1 is a subsequence of string2. A subsequence can be derived by deleting some elements without changing the order of the remaining elements.

• What considerations should be made when testing hundreds of hypotheses with many t-tests? When conducting multiple t-tests, you need to consider the risk of Type I errors due to multiple comparisons. How would you control for this, and what statistical methods would you use to adjust for multiple testing?

• How does random forest generate the forest and why use it over logistic regression? Explain how random forest generates multiple decision trees and aggregates their results. Discuss the advantages of using random forest over logistic regression, such as handling non-linear data and reducing overfitting.

• How do we deal with missing square footage data in housing price predictions? You have 100K sold listings with 20% missing square footage data. Describe methods to handle missing data, such as imputation techniques or using algorithms that can handle missing values directly.

• How would you combat overfitting in tree-based models? When training a classification model, explain strategies to prevent overfitting in tree-based models, such as pruning, using ensemble methods like random forests, or applying cross-validation.

• Will increasing the number of trees in a random forest always increase accuracy? Discuss the impact of increasing the number of trees in a random forest model on accuracy. Explain the concept of diminishing returns and the point at which adding more trees may not significantly improve performance.

• How would you implement k-means clustering in Python from scratch? Given a two-dimensional NumPy array data_points, number of clusters k, and initial centroids initial_centroids, describe the steps to implement the k-means clustering algorithm. Return a list of cluster assignments for each data point.

• How would you explain what a p-value is to someone who is not technical? Explain the concept of a p-value in simple terms to someone without a technical background. Use analogies or everyday examples to make it understandable.

• What should you do if home prices are skewed to the right in a predictive model? You are building a model to predict real estate home prices in a city, and the distribution of home prices is skewed to the right. Should you take any action, and if so, what should you do? Additionally, consider what to do if the target distribution is heavily skewed to the left.
