The Andela Standard: Network Entrance Assessments

Machine Learning engineers are instrumental in crafting, enhancing, and sustaining machine learning applications. Working collaboratively across teams, they ensure the effective integration of machine learning components, optimize application performance, and resolve intricate challenges. Successful candidates exhibit proficiency in machine learning, demonstrate a deep understanding of data science architecture, and showcase problem-solving skills in dynamic software environments.

1. Qualifications

Qualification criteria:

  • A minimum of 4 years of professional experience in a Machine Learning Engineer role (excluding intern and volunteer experience).
  • A bachelor's degree in a technology-related field or equivalent work experience.
  • Excellent spoken and written English communication skills.
  • Proficient in machine learning with a solid understanding of data science principles.
  • Hands-on experience with machine learning technologies, including data preprocessing, model development, and familiarity with machine learning libraries.
  • Strong problem-solving skills, attention to detail, and a results-oriented mindset in the realm of machine learning engineering.
  • A commitment to continuous learning and adapting to evolving technologies in the machine learning domain.
  • A collaborative and team-oriented approach to projects.

2. Skill Validation

This qualification assessment tests the candidate's knowledge of Machine Learning Engineering fundamentals. It's composed of Q&A and code challenges that evaluate the candidate's theoretical knowledge and hands-on skills. A candidate is approved in this test if all challenge level cut-off scores are met.

Machine Learning Fundamentals

This challenge is designed to assess the knowledge and skills of mid-senior engineers in Machine Learning. It consists of questions about Machine Learning fundamentals, including concepts and features, as well as practical questions exploring scenarios Machine Learning engineers typically find in real-world applications.

SQL

This challenge tests candidate knowledge of SQL and associated best practices. The question difficulty ranges from basic to intermediate, so the challenge should be suitable for any experienced SQL practitioner. Most of the questions are derived from SQL certifications and some inspired by frequent SQL interview questions.

Pandas Code Challenge

This challenge involves the use of Pandas to merge two World Factbook datasets and select countries with the highest obesity rates. Candidates can merge CSVs and perform fundamental operations on dataframes such as renaming, resetting indices, merging, sorting and selecting.

3. Technical Interview

This assessment is designed to test the candidate's practical knowledge of Machine Learning Engineering. Candidates who pass this challenge are able to work with Machine Learning to implement Machine Learning models.

During the assessment, candidates will tackle a hands-on problem tailored to real-world scenarios in Machine Learning Engineering. Their solution will be first verified by a battery of automated test cases to ensure it meets the functional requirements as well as industry standards. Then, our experienced interviewers will step in to assess the overall efficiency of the candidate's solution.

Assessment Outline:

  • Machine Learning Challenge (Option 1):
    • This is an intermediate-to-advanced-level problem that asks the candidate to write a function to remove outliers from a data set. They'll need to remove the outliers from the dataset given a cutoff passed as a parameter to the function together with the original dataset.
  • Machine Learning Coding Challenge (Option 2):
    • The first challenge is is a basic Pandas problem that asks a tests basic skill in grouping and selecting. Given a simple two-column table, the candidate should find groups in columns a that have a specific value in any column b within that group.
    • The second challenge is a basic NumPy challenge which tests comfort with arrays and masking. The candidate should chop the tops off an array in NumPy.
