How to structure the interview to assess skills and cultural fit for {role_name}

Work sample test (Home assignment)

Recruitment Bullet

Assess the candidate’s practical skills by assigning a real-world task similar to the work they would do if hired.

  • Title: Develop a Predictive Model for Healthcare Data
  • Objective: To assess the candidate’s ability to design and implement a machine learning model that predicts patient outcomes based on a dataset.
  • Requirements:
    • Use a real or simulated healthcare dataset.
    • Apply appropriate data preprocessing techniques.
    • Build and evaluate a machine learning model (e.g., logistic regression, decision tree, or deep learning model).
    • Document the steps, methodologies used, and provide a brief report on the findings.
  • Time Frame: 5 days to complete the task and submit the code, documentation, and report

Questions based on home assignment :

Once done with work sample test evaluate the candidate’s technical proficiency based on the work sample task.

Technical questions

Recruitment Bullet

Duration : 10 minutes/question

  • Question: "Describe the steps you took to preprocess the healthcare dataset before feeding it into your machine learning model."
    • Expected Answer: The candidate should mention steps like handling missing values, normalizing or standardizing features, and splitting the data into training and testing sets.
    • Sample Answer: "I began by identifying and handling missing values through imputation, then normalized the numerical features to ensure they were on a similar scale. Finally, I split the dataset into 70% training and 30% testing data to validate the model’s performance."
  • Question: "Which machine learning model did you choose, and why did you select it for this healthcare dataset?"
    • Expected Answer: The candidate should justify the choice of model based on the dataset characteristics, problem type, and expected outcomes.
    • Sample Answer: "I chose logistic regression because the problem was a binary classification task. The simplicity and interpretability of logistic regression made it a suitable choice for predicting patient outcomes."
  • Question: "How did you evaluate the performance of your model, and what were the results?"
    • Expected Answer: The candidate should discuss evaluation metrics such as accuracy, precision, recall, F1-score, and explain the results.
    • Sample Answer: "I evaluated the model using accuracy and F1-score as the primary metrics. The model achieved an accuracy of 85% and an F1-score of 0.82, indicating a good balance between precision and recall."

Behavioral questions

Recruitment Bullet

Duration : 10 minutes/question

  • Question: "Tell me about a time when you encountered a significant challenge while working on an AI project. How did you overcome it?"
    • Expected Answer: The candidate should describe a specific challenge, their approach to resolving it, and the outcome.
    • Sample Answer: "During a previous project, I faced issues with imbalanced data, which led to poor model performance. I addressed this by using techniques like SMOTE to balance the classes, which improved the model’s accuracy significantly."
  • Question: "How do you prioritize tasks when working on multiple AI projects simultaneously?"
    • Expected Answer: The candidate should demonstrate effective time management and prioritization skills, considering project deadlines and impact.
    • Sample Answer: "I prioritize tasks based on deadlines and the importance of each project. I use project management tools to track progress and ensure that critical tasks are completed first, allowing me to manage multiple projects efficiently."
  • Question: "Can you describe a situation where you had to explain complex AI concepts to non-technical stakeholders? How did you ensure they understood?"
    • Expected Answer: The candidate should provide an example of how they simplified complex concepts and communicated effectively with non-technical stakeholders.
    • Sample Answer: "In a previous role, I had to explain a machine learning model’s outcomes to a client with little technical background. I used analogies and visual aids, like graphs, to convey the model’s predictions and the factors influencing them, ensuring the client fully understood the insights."

How to evaluate and compare candidates after interviews?

After interviews, it's important to evaluate and compare candidates based on a set of predefined criteria.Use scorecard to evaluate each candidate.
