Mastering Prescreening: What Questions to Ask Decentralized Finance (DeFi) Engineer
As the DeFi sector becomes increasingly popular, companies are in constant search of capable hands that can handle its complex nature. But, how do you sieve through and identify the very best? Pre-screening questions are the answer. Let’s dive into the questions you should be asking potential hires to ensure your projects reach great heights.
Blockchain Technologies and Cryptocurrencies
The first question you should ask is about their experience with blockchain technologies and cryptocurrencies. An answer to this will give you a glimpse into their knowledge or experience in the field.
Understanding DeFi
Yes, we know explaining DeFi to a non-technical individual seems like trying to explain rocket science to a toddler. But, a good hire should be able to simplify the complexities of DeFi in an easy, digestible manner.
Programming Languages
DeFi engineering is a whole new ballgame. It’s important to understand what programming languages they're comfortable with in DeFi context, since it forms the backbone of most operations.
Familiar DeFi Protocols or Platforms
Understanding what DeFi platforms or protocols they’re familiar with helps to know their breadth of knowledge. It could be MakerDao, Compound, Uniswap, or others. Whichever it is, it’s a plus for your organization.
Role of Smart Contracts in DeFi
Smart contracts are integral to DeFi. Your potential hire should have a solid understanding of its function, and better still, have examples of how they have used them.
Securing DeFi Applications
In the era of increasing online threats, how they ensure the security of DeFi applications is a question not to be overlooked.
Experience with Ethereum and Other Blockchain Platforms
Ethereum is a key player in the DeFi space. An understanding and familiarity with Ethereum and other blockchain platforms like Tron, Binance Smart Chain can be advantageous.
Yield Farming
Yield farming is a common trend in DeFi. It would help to know if they have an understanding of it and experience in yield farming project.
Blockchain Programming Languages like Solidity
Solidity is a top choice for many blockchain programmers. Finding out their proficiency in Solidity and other similar languages is a must.
Use of Decentralized Exchanges (DEXs) and Decentralized Crowdfunding
Their experience with Decentralized Exchanges (DEXs) will tell if they have a good understanding of peer-to-peer transactions. Concurrently, their exposure to ICOs and decentralized fundraising can add significant value to your team.
Understanding of Liquidity Pools and Automated Market Makers (AMMs)
Both Liquidity Pools and AMMs play crucial roles in DeFi. Ensuring they have a comprehensive knowledge about them is essential.
Lending and Borrowing in DeFi
Lending and borrowing, a prime functionality of DeFi, is something that your hire must understand in and out.
Concept of Staking in DeFi
Staking is another key aspect of DeFi. Gauge their deep understanding and experience skill in this landscape.
Experience with Blockchain Testing Tools and Frameworks
Since testing and debugging is quintessential in any code development process, having experience with blockchain testing tools can give them an edge.
Tackling Scalability and Speed Issues
Ask them if they have dealt with scalability and speed issues in a DeFi context, a common problem with blockchain-based applications.
Understanding of Over-collateralization and Under-collateralization
Last but not least, understanding the risks involved and risk management strategies like over-collateralization and under-collateralization is fundamental in DeFi space.
