Top 10 Johns Hopkins APL Interview Questions

Here are the 10 most common questions asked at APL interviews with tips to craft winning responses:

1. Walk me through your resume.

This is frequently used to kick off APL interviews. They want to learn about your background and give you a chance to highlight your most relevant experience.

How to Tackle It:

• Concisely summarize your background, career progression, and domains you’ve worked in.

• Emphasize projects, skills, and impact that directly pertain to the role.

• Be prepared to elaborate on any item they ask about.

Sample Response:

After earning my electrical engineering degree from UT Austin, I started my career at Lockheed Martin rotating through the avionics integration and missile defense teams. I led cross-functional design reviews and failure investigations. This allowed me to hone technical troubleshooting and project management skills.

For the past 3 years, I’ve been an R&D test engineer at Northrop Grumman. My primary focus has been developing test automation frameworks for radar systems. I personally designed the fault injection framework now used across 8 major programs. Outside of work, I serve as a robotics mentor for local high school teams to stay engaged with applied engineering challenges.

2. Why are you interested in APL?

APL wants to gauge your passion for their mission and assess cultural fit. This open-ended question also tests your research on the company.

How to Prepare:

• Show your enthusiasm for APL’s critical, life-changing work.

• Demonstrate a deep understanding of their technical focus areas that excite you most.

• Share specific details on projects or teams you’d love to contribute to.

• Convey alignment with their collaborative values and problem-solving culture.

Sample Response:

I’ve been incredibly impressed by APL’s renowned expertise in autonomous systems. Your pioneering work aligning autonomy, robotics, and artificial intelligence with naval needs is exactly the type of challenge I want to help drive forward. I also thrive in APL’s collaborative culture where diverse teams come together to solve multifaceted problems. Being able to quickly iterate on solutions that have national impact is very appealing to me.

Specifically, I would be thrilled to join the Air and Missile Defense Sector to improve threat detection and response capabilities. Developing algorithms and architectures that protect lives aligns perfectly with my interests and strengths.

3. How do you handle a tight deadline on a team project?

Collaboration and time management are essential skills at APL, so expect questions on both. This checks your abilities under pressure.

How to Stand Out:

• Demonstrate you stay focused on end goals and avoid micromanaging.

• Share examples of how you rallied your team without sacrificing quality.

• Emphasize listening, empathy, and keeping team morale up.

• Discuss how you identified and eliminated roadblocks.

Sample Response: When my team was developing a new AI training dataset, we realized 3 weeks before launch that we needed 10x more labeled data than expected. I immediately met with each engineer one-on-one to map dependencies and identify our most critical paths. Together we decided that outsourcing a portion of data labeling was our fastest option.

I coordinated with leaders across departments to acquire additional budget and resources needed. My priority was keeping the team focused on our end goal while shielding them from unnecessary pressure. With open communication and a lot of late nights, we worked closely to rapidly expand our dataset without sacrificing quality. In the end we achieved our deadline, with all of us learning valuable lessons about scoping data projects.

4. Tell me about a time you failed. What did you learn?

Don’t be thrown off by this question – APL wants to see your attitude when faced with setbacks. The key is demonstrating maturity and self-awareness.

How to Impress Them:

• Choose an appropriate failure where you played a central role. Pick something technical over interpersonal.

• Take ownership – don’t blame external factors or other people.

• Share the specific actions you took to rebound from the failure.

• Emphasize the lessons you learned about the process, yourself, and how you later applied those lessons to succeed.

Sample Response: Early in my last role, I was assigned to lead prototyping for a new unmanned underwater vehicle. This was the first time I spearheaded designing a full system from scratch. Looking back, I tried to take on too much technical work myself rather than effectively leveraging my team’s strengths.

When we fell behind schedule, I was overly confident we could catch up and hesitated to flag risks. The end result was we had to redo major portions of the prototype when it failed preliminary tests. From this experience I learned the importance of delegating tasks based on individuals’ talents, while also keeping leadership updated on roadblocks early and often. Most importantly, I learned to ask for help when in over my head. Utilizing my team’s skills and being transparent about challenges has helped lead to on-time delivery in all my projects since.

5. Tell me about a time you had a conflict with a coworker. How was it resolved?

APL wants to understand your conflict management style and assess your people skills. There are no “right” answers here – they’re looking for maturity and empathy.

How to Stand Out:

• Focus your story on listening, finding common ground, and compromising.

• Share how you proactively resolved the conflict directly with your coworker.

• Emphasize maintaining a professional tone and repairing team cohesion.

• Discuss the positive outcome and lessons learned about working through disagreements.

Sample Response: My colleague and I strongly disagreed on the best algorithm to use for an oceanographic data processing pipeline we were jointly developing. I felt my method was more accurate while he believed his approach was faster. We initially got caught up asserting our correctness, which caused rising tensions.

After taking a step back, I sat down with my colleague to better understand his perspective. I asked for his help walking through his proposed solution in depth, and he did the same for my approach. Through this open conversation, we realized we had talked past each other and both algorithms had merit. We ultimately blended aspects of each method, combining accuracy and speed. This collaboration taught me how quick discussions to understand different viewpoints can unlock creative solutions while strengthening team relationships.

6. How do you ensure you have the most up-to-date technical knowledge and skills in your field?

APL needs team members who are self-driven to continuously build their expertise. This question tests your dedication to lifelong learning.

How to Stand Out:

• Demonstrate you proactively seek out learning opportunities rather than wait for training.

• Share specific examples like online courses, certifications, conferences, and more.

• Highlight how you put new skills/knowledge into practice to improve your work.

• Discuss how you enjoy mentoring and training others to raise team abilities.

Sample Response: *To stay current in AI, I dedicate time every week to learning new developments and best practices. I regularly complete online courses and certifications through venues like Coursera to expand my skillset. I also attend local AI meetups and national conferences like NeurIPS to connect
