FAQs

Start by listing what you want the data scientist to achieve. Do you need data analysis, predictive modeling, or data visualization? Be clear about the final goals and deadlines. It's like creating a map before a journey.
A good job description has the right keywords. Include the type of data, tools or software like Python or R, and your industry. Mention the size of the data set and any special skills you need. It's like writing a wish list for a birthday.
Think about the complexity of your project. Do you need experience in machine learning or simple data cleaning? Check their portfolio and past work. It's like picking a toy level, beginner, intermediate, or expert.
Break the project into smaller tasks with deadlines. See how long similar projects took to finish. Balance between speed and quality. It's like setting a timer when baking cookies; you don’t want them burnt or undercooked.
Set clear milestones and review them regularly. Provide feedback and make changes if needed. It's like building a Lego tower—step by step, making sure each piece fits.
Provide access to databases, software, and anything they need to work. Check if they prefer any specific tools, like Jupyter notebooks. Think of it like giving them colored pencils for coloring.
Use regular check-ins, emails, or calls. Share updates and ask for them too. It's like keeping in touch with a pen pal, making sure everyone knows what’s happening.
Request detailed documentation explaining the data, methods, and findings. This helps you understand and use the results. It’s like getting instructions with a new toy, so you know how to play with it.
Look at their portfolio and read case studies. Check for successful outcomes and tools used. It's like reading book reviews before buying a new book to know if you'll like it.
