In this section, we’ll review the various interview questions that might be asked during a Data Scientist interview at Con Edison. The interview process will likely focus on a combination of technical skills, problem-solving abilities, and your fit within the company culture. Be prepared to discuss your past experiences, technical knowledge, and how you can contribute to the team.

Technical Skills

1. Can you explain a machine learning model you have implemented in the past?

This question assesses your practical experience with machine learning and your ability to communicate complex concepts clearly.

How to Answer

Discuss the model's purpose, the data you used, and the results you achieved. Highlight any challenges you faced and how you overcame them.

Example

“I implemented a random forest model to predict energy consumption based on historical usage data. I faced challenges with feature selection, but by using recursive feature elimination, I improved the model's accuracy by 15%. The insights helped the company optimize energy distribution.”

2. Describe a situation where you had to analyze a large dataset. What tools did you use?

This question evaluates your data analysis skills and familiarity with relevant tools.

How to Answer

Mention the dataset, the tools you used (like Python, SQL, or R), and the insights you derived from your analysis.

Example

“I analyzed a dataset of customer usage patterns using Python and Pandas. By cleaning the data and applying clustering techniques, I identified key segments that allowed the marketing team to tailor their campaigns effectively.”

3. How would you approach a problem where the data is incomplete or missing?

This question tests your problem-solving skills and your understanding of data integrity.

How to Answer

Discuss strategies for handling missing data, such as imputation techniques or using algorithms that can handle missing values.

Example

“In cases of missing data, I first assess the extent of the missingness. If it's minimal, I might use mean imputation. For larger gaps, I would consider using models that can handle missing values directly, or I might analyze the data to understand if the missingness is informative.”

4. Can you write a SQL query to find the second highest salary from a table?

This question evaluates your SQL skills and ability to write efficient queries.

How to Answer

Explain your thought process before writing the query, and ensure you understand the underlying database structure.

Example

“To find the second highest salary, I would use a subquery: SELECT MAX(salary) FROM employees WHERE salary < (SELECT MAX(salary) FROM employees); This efficiently retrieves the second highest salary without needing to sort the entire dataset.”

5. What is your experience with data visualization tools? Which do you prefer and why?

This question assesses your ability to communicate data insights visually.

How to Answer

Discuss your experience with various tools and why you prefer one over the others based on your experiences.
