UX designer interview questions test whether a candidate can turn user research, business constraints, and product goals into interfaces that people actually use, not just visually appealing mockups that fall apart under real-world conditions.

That is the clean definition.

The sharper one is this: companies hiring UX designers in 2026 are not looking for candidates who can name design principles. They are looking for designers who can navigate ambiguity, defend decisions with evidence, collaborate across engineering and product, and ship work that measurably improves user outcomes.

In FinTech and HealthTech environments, where Code & Pepper’s engineering and design teams operate, UX designers must also design for compliance contexts, regulatory-sensitive data flows, and users who make high-stakes financial or medical decisions. That makes the interview bar significantly higher.

This guide covers the UX designer interview questions that appear most frequently in hiring processes in 2026, what strong answers look like, and how to demonstrate the depth interviewers are actually evaluating.

Machine learning engineer interview questions test whether a candidate can build ML systems that work in production, not just explain algorithms on a whiteboard.

That is the clean definition.

The sharper one is this: companies hiring ML engineers in 2026 are not looking for textbook recall. They are looking for engineers who can turn models, data pipelines, and product requirements into working software that scales, handles edge cases, and does not degrade silently under real-world load. 

In FinTech and HealthTech environments, where Code & Pepper’s engineering teams operate, ML engineers must also navigate strict data privacy requirements under GDPR and HIPAA, making interview preparation even more demanding.

This guide covers the machine learning engineer interview questions that appear most frequently in technical hiring processes, what strong answers look like, and how to demonstrate the depth interviewers are actually evaluating.

Explore the impact of Big Data, AI, and machine learning on personalized treatment in healthcare.

Traditionally, we put trust in banks to look after our financial data. In the past, they were the only ones with access to this sensitive information which they could use to their advantage.  This has changed with the PSD2, a directive issued by the EU in 2015 according to which incumbent banks were obliged to recognise customers as the rightful owners of their financial data and to provide them with the opportunity to decide who they want to share this information with. Open banking became a reality.

Arrival of a new technology always stirs up a lot of emotions. It is either met with wild enthusiasm or fierce criticism. This is because of its disruptive potential which both creates new opportunities as well as threatens the status quo. This love and hate dynamic also applies to blockchain. Initially associated with Bitcoin it was criticised for high-energy consumption. Blockchain technology, however, also has its merits such as: transparency, independence and security. That’s why it started to be used in a variety of sectors and for a range of purposes such as secure sharing of medical data or supply chain and logistics monitoring. Our new Ask Me AnyFin guest, Toni Caradonna makes use of blockchain to support nature conservation communities. How does he do it? Find out in the Ask Me AnyFin interview. 

There are many sources of inspiration in business. One of them is technology which both feeds on new ideas and breeds them. This is, particularly, true for financial technology which relies heavily on communication technology. These two: money and the Internet create the most powerful media duo in the world.

His company, Mintos, is a virtual marketplace which offers a new investment asset. We invited him to our Ask Me AnyFin conversation to learn more about his offering and the details of his entrepreneurial journey.
