Describe a challenging problem you've faced in BCI calibration and how you resolved it.

Everyone loves a good problem-solving story. Maybe they faced erratic signals due to environmental noise or a participant's excessive movement. Hearing about their challenges and solutions can give you insight into their ingenuity and perseverance.

What steps do you take to prepare participants for EEG data collection?

Participant preparation can make or break an EEG session. From explaining the procedure to ensuring comfort, they're all crucial steps. What kind of instructions or practice runs do they use? This can show you their level of thoroughness and consideration.

How do you handle the cleaning and maintenance of BCI equipment?

BCI equipment isn’t cheap, and keeping it in top shape is essential. Do they have a routine for cleaning electrodes and checking for wear and tear? Proper maintenance can save time and money in the long run.

What experience do you have in creating and running experimental protocols?

Experimentation is at the heart of BCI research. Have they designed protocols from scratch or implemented existing ones? Knowing their experience here can help you gauge their ability to manage and execute studies.

Can you discuss any experience you have with machine learning algorithms in BCIs?

Machine learning and BCIs are like peanut butter and jelly—they go hand in hand. Whether it’s feature extraction or classification algorithms, understanding their expertise in this area can tell you a lot about their skill set.

How do you stay current with advancements in the BCI field?

The BCI field is ever-evolving. How do they keep up? Do they read journal articles, attend conferences, or participate in webinars? Their methods can show you how invested they are in staying ahead of the curve.

What strategies do you use to minimize noise and artifacts in brain signal recordings?

Noise and artifacts are the pesky gremlins of brain signal recordings. Whether it's through software filters or hardware adjustments, their strategies can tell you a lot about their hands-on experience and knowledge.

Describe your experience with regulatory and ethical considerations in BCI research.

Ethics and regulations are non-negotiable in research. Do they follow specific guidelines or have experience with Institutional Review Boards (IRBs)? Understanding their familiarity with these aspects ensures they're conducting responsible research.

Can you provide an example of a successful BCI calibration project you worked on?

Success stories are always inspiring. Maybe they optimized a system for faster response times or improved accuracy. Their examples can provide a glimpse into their practical skills and achievements.

What are some of the common challenges in BCI system calibration, and how do you address them?

Calibration can be a tricky beast. From varying brain signals to electrode placement issues, each challenge requires a unique solution. Understanding how they tackle these problems can give you insight into their problem-solving abilities.

How do you document and report your findings to other team members or stakeholders?

Communication is key, especially in a research setting. Do they create detailed reports, use visualization tools, or hold regular meetings? Their documentation and reporting methods can show their organizational skills and ability to collaborate.

Describe your experience with participant recruitment and consent processes in BCI studies.

Recruitment and consent are foundational to ethical research. Have they designed consent forms or managed participant databases? Their experience in this area is crucial for following ethical guidelines and ensuring smooth study execution.

Can you talk about any experience you have had presenting your work or findings at conferences or meetings?
