How to find the best chatbot developer?
Now that you understand the chatbot development skill requirements, you can initiate the hiring process. Do the following:
1. Choose a platform to hire chatbot developers
Companies in various industries hire freelancers nowadays, and you might be thinking of this option too. You might even get freelancers at a low hourly rate. We, however, strongly encourage you to focus on your business needs.
Hiring freelancers can expose you to various risks, e.g.:
- You will find it hard to evaluate the relevant skills of freelancers.
- Freelancers work part-time on a project, and you might not get adequate contributions from them.
- Managing freelancers can be hard. If you hire remote chatbot developers on a freelance platform, project management becomes harder.
- Freelancers might leave a project mid-way. In that case, you need to hire replacement developers.
- You can’t get any project management support from freelance platforms.
You can deliver a superior customer experience by hiring chatbot developers from DevTeam.Space instead. We have a proven track record as a chatbot development company. DevTeam.Space offers the following advantages:
- Dedicated developers with skills, experience, and motivation;

2. Interview chatbot developers
You have posted your job ad and received resumes. You now need to interview candidates. If you hire developers from DevTeam.Space, then you don’t need to take extensive interviews. We already do the heavy lifting for you, thanks to our comprehensive vetting process!
You need to take very detailed interviews if you hire freelancers though. Our interview questions can help. The following are a few examples:

us since 2016
You should cover all relevant technical areas during the interview. Avoid asking only theoretical questions.
Ask questions to evaluate how developers solved problems in their past projects. You can explain your project requirements and ask how they would approach such projects. Look for specific answers and not jargon.
3. Get chatbot developers started on your project
You need developers to become productive quickly. An effective onboarding process goes a long way toward that. Do the following:
- Explain the project requirements and technical solutions to the new team members.
- Share the relevant project documents.
- Grant the required access to the new developers.
- Explain the project plan, schedule, work intake processes, and work approval processes.
- Introduce the new developers to your existing team and explain the roles and responsibilities.
- Set up an effective communication process.
Interview tips to hire chatbot developers
The following interview tips might help you:
1. Ask questions relevant to your project
You should ask questions that have relevance to your project requirements. For example, if you want to use the Microsoft Bot development framework, evaluate candidates for this skill.
Alternatively, do you need to launch voice-enabled chatbots? Check whether developers have worked on such projects.
Are you interested in Facebook chatbots or Telegram bots? Ask candidates whether they have developed such bots.
2. Look for sufficiently senior developers if you have a complex project
Do you plan to launch chatbots with strategic objectives? Perhaps you want to analyze customer behavior and improve business operations based on the findings. That’s quite different from simple chatbots that improve efficiency by automating simple tasks.
It takes a complex chatbot to enhance customer experience considerably or streamline operations. Such chatbots need to have considerable self-learning abilities.
On such projects, you need senior developers who work closely with end-users to understand the requirements. Hire developers suitable to the complexity of your project.
3. Choose service providers that respond to your dynamic business requirements
Your business requirements might change often. Hire developers from a company that can adequately respond to dynamic requirements.
To take an example, you had earlier planned to hire chatbot developers only. You found later that your existing team is too stretched. Therefore, you need developers to create websites, mobile apps, and messaging apps too. Your service provider should be able to provide web/mobile developers at short notice.
Alternatively, let’s assume you wanted to take the cost advantages of hiring remote chatbot developers. You don’t want additional project management overhead though. Your service provider should be able to provide project management support in addition to remote programmers.

Examples of interview questions to ask when hiring chatbot developers
Check out the following examples of interview questions
1. Why is data normalizing important when developing chatbots?
Data normalizing is an important step in many AI/ML/NLP development projects. You use the data normalizing process to organize data sets for training and testing. You will use specific formats for organizing data. These formats make it easy for your AI/ML/NLP system to read and understand the data sets.
Now, a chatbot needs to understand inputs from users. Different users might enter their inputs in different ways. Your chatbot needs to read different formats of inputs accurately. Therefore, you should train it with data organized in various formats. You use data normalizing to prepare data into those formats.
2. Which key risks should be mitigated when creating a technical solution for, or developing, an AI chatbot?
Architects creating technical solutions for AI chatbot development, or developers creating such bots, should mitigate the following key risks:
- The chatbot might not understand the requests from users.
- Chatbots might not understand the context of queries from users.
- The chatbot might stop responding, requiring users to start the flow of conversation again.
- Chatbots might respond slowly.
- Users might get incorrect information from the chatbot.
- The chatbot might not complete the tasks expected from it.
- The user interface of the chatbot might be hard for users to understand.
3. How will you match patterns of words and phrases to keywords while training an AI chatbot?
AI chatbot developers should use AIML (Artificial Intelligence Markup Language) for this. They should write pattern templates using AIML for training chatbots. In these pattern templates, they should match keywords to word and phrase patterns.
