Apple MLE Round 2: Technical Interviews

Overview

For the second round, you should expect to face one or more these rounds:

  1. ML Rounds: In this round, the questions will be specific to the hiring team's domain. For example, candidates might be asked to solve a probability calculation question based on dynamic programming or answer questions related to NLP. The purpose of this round is to assess the candidate's ability to apply their technical skills to real-world problems in the specific domain that the hiring team is focused on.
  2. Coding Rounds: In this round, candidates will be asked Leetcode questions and their DSA skills will be evaluated. For example, one candidate reported being asked to implement a simpler version of Naive Bayes or Association Rules. Another candidate reported that the hiring team sent a link for audio-related data processing for a coding challenge. The purpose of this round is to assess the candidate's coding skills and ability to solve problems efficiently.

Interview Questions

  • What's the BERT model and why is it good?
  • Explain the concept of dynamic programming and how it can be used in probability calculations?
  • How would you approach solving a natural language processing problem? Can you give an example of a problem you've solved in this area?
  • Implement a simpler version of Naive Bayes.
  • How would you implement Association Rules? Can you walk me through the steps?
  • Given a dataset, implement a program to process the audio data. Can you explain your approach and any challenges you faced?

Apple MLE Round 3: Final Interview Rounds

Overview

The final round will likely involve a techno-behavioral interview followed by a managerial round with behavioral questions.

One candidate reported giving a presentation about their research. The presentation will be followed by a Q&A session, during which people from the team will ask the candidate questions about their research. This is an opportunity for the candidate to showcase their technical knowledge and communication skills.

The final round will be a managerial round with behavioral questions. The interviewer will ask you questions related to their managerial skills and how they handle certain situations. For example, you might be asked about your experience managing a team or how you would handle a difficult team member.

Please note that this round is role specific and you might encounter a different case depending on the role you are applying for.

Interview Questions

  • How do you prioritize your workload when you have multiple tasks to complete within a short timeframe?
  • Describe your experience managing a team? What were some of the challenges you faced and how did you overcome them?
  • How do you handle conflicts within a team? Can you give an example of a time when you successfully resolved a conflict?
  • How do you approach problem-solving when faced with a difficult technical challenge?
