Whether you're reached out to by an S&P Global recruiter or take the initiative to apply yourself, make sure to carefully review the job description and tailor your CV according to the listed prerequisites.
Tailoring your CV may involve incorporating specific keywords that the hiring manager might be looking for and crafting a targeted cover letter. Highlight your relevant skills, experiences, and achievements that align with the job requirements.
Should your CV pass the initial screening, a recruiter from S&P Global will get in touch to verify key details, such as your work history and skill level. This call may also include some behavioral questions to gauge your cultural fit with the company.
In certain cases, the Data Engineering hiring manager may also be present during the screening call to further discuss the role and answer any questions you may have. They might delve into surface-level technical and behavioral topics as well.
The recruiter screening call usually lasts around 30 minutes.
Successful candidates from the initial screening will be invited for a technical virtual interview. This stage typically involves video conferencing and screen sharing tools. The interview, which usually lasts around an hour, can cover a range of topics crucial for the Data Engineer role at S&P Global.
Expect questions about Python programming, ETL pipelines, SQL queries, and data manipulation. You may also be given problems related to automation, machine learning, and data engineering processes to solve in real-time.
Depending on the role, you might also receive a take-home assignment focusing on data extraction, transformation, and automation of data processes.
After clearing the technical virtual interview, you'll move on to the onsite interview loop, which often involves multiple rounds. During these rounds, you will engage with various team members and stakeholders who will evaluate your technical skills in-depth, including coding and systems design.
You will also have the opportunity to demonstrate your problem-solving abilities through practical exercises or whiteboard sessions. If a take-home assignment was given in the prior stage, you might need to present your solution as part of the interview.
The final interview round, often with senior leadership or team leads, aims to assess your strategic thinking, long-term career goals, and cultural fit. By this point, the focus shifts more towards your alignment with S&P Global’s mission, values, and how you might contribute to upcoming projects within the Data Engineering team.

, and temperature
. Write a Python function using Pandas that uses linear interpolation to estimate the missing data and fill out the dataframe. The interpolation should only consider data from the same city. Assume no missing data two days in a row and that both the first and last dates hold valid temperature data.How does random forest generate the forest and why use it over logistic regression? Explain how random forest generates multiple decision trees and combines their results. Discuss the advantages of using random forest over logistic regression, such as handling non-linear data and reducing overfitting.
When would you use a bagging algorithm versus a boosting algorithm? Compare two machine learning algorithms. Describe scenarios where bagging (e.g., random forest) is preferred for reducing variance and boosting (e.g., AdaBoost) is preferred for reducing bias. Provide examples of tradeoffs between the two.
How would you evaluate and compare two credit risk models for personal loans?
List metrics to track the success of the new model, such as accuracy, precision, recall, and AUC-ROC.
What’s the difference between Lasso and Ridge Regression? Explain the differences between Lasso and Ridge Regression, focusing on their regularization techniques.
