Hundreds of Hypotheses

You are testing hundreds of hypotheses with many t-tests. What considerations should be made?

Let’s say we have a table with an <code>id</code> and <code>name</code> fields. The table holds over 100 million rows and we want to sample a random row in the table without throttling the database.

Write a query to randomly sample a row from this table.

Input:

<code>big_table</code> table

<table>
<thead>
<tr>
<th>Columns</th>
<th>Type</th>

Write a query to randomly sample a row from a big table.

Random SQL Sample

Let’s say you work for a social media company that has just done a launch in a new city. Looking at weekly metrics, you see a slow decrease in the average number of comments per user from January to March in this city.

The company has been consistently growing new users in the city from January to March.

What are some reasons why the average number of comments per user would be decreasing and what metrics would you look into?

What metric could be used to measure if active users are still engaging on the platform despite an overall decrease in the average number of comments per user?

What metric could be used to measure if active users are still engaging on the platform despite an overall decrease in the average number of comments per user?

About LegalZoom
We're here to make legal help accessible to all. LegalZoom transformed the legal industry with the launch of our online services and groundbreaking technology in 2001. Since then, millions of customers have counted on us to officially start and run businesses, protect brands and intellectual property, and look after loved ones through wills and trusts. As the industry leader for over 20 years, innovation remains at the center of all we do. We're creative thinkers and problem solvers with a passion for building legal and tax products that make a positive impact on the world, and we're always looking for exceptional people to push us further. With us, you'll do work that's as rewarding as it is challenging with a team where every voice matters and diversity, equality, and inclusion are truly embraced. Together, we'll continue to democratize the law and make a real difference in the lives of millions.
Remote Environment
At the end of 2021, LegalZoom officially committed to being a remote-first company. Remote-first means that Zoomers are not expected to come into an office for a fixed number of days outside of those employees identified as essential onsite workers. While we remain a remote-first culture, our local offices have evolved as collaboration spaces for Zoomers to meet and engage in person. This position will be 100% remote and is not required to come into the office.

Design and conduct machine learning experiments, utilizing A/B testing, reinforcement learning, and causal inference, to validate hypotheses and optimize models.
Interpret results of ML models and experiments to make strategic and tactical recommendations to enhance customer engagement and internal efficiencies.
Develop scalable data pipelines and models to support the implementation of LLMs and other ML systems, ensuring robust, reliable performance.
Collaborate closely with Product, Engineering, Sales, and Operations teams to integrate ML/LLM solutions into their workflows and ensure they have the data-driven insights they need.
Continuously improve the team's machine learning codebase and best practices, with a focus on scalability, performance, and data hygiene.
You have:
M.S. or Bachelor's degree in Computer Science, Engineering, Data Science, Mathematics, Statistics, or related quantitative field. (If M.S. degree, a minimum of 2+ years of industry experience required; if Bachelor's degree, a minimum of 3+ years of industry experience with ML models and systems).
Expertise in Machine Learning algorithms and LLM architectures (e.g., transformer models, GPT-based models).
Experience in developing, fine-tuning, and deploying LLMs and other advanced ML models in production environments.
Proficiency in Python.
Experience with cloud-based platforms and ML infrastructure (e.g., AWS, GCP, Azure) to scale model development and deployment.
Advanced SQL expertise for data manipulation and analysis.
Strong communication skills to explain complex ML and LLM concepts to non-technical stakeholders and influence decision-making at the leadership level.
Remote Employees should confirm that the internet service available has adequate bandwidth to support all work processes.
