A Detailed Checklist For Hiring Python Developers


Table of Contents


Python is today’s one core technology. It is everywhere starting from web development, e-commerce development, game development, machine learning development, artificial intelligence development and the list goes on. To compete in this ever-changing tech scenario, hiring python developers with relevant skills is crucial. 

Technology is advancing much faster and their adoption is too. Python as a language is rapidly transforming the digital world causing an abundance of Python developer jobs. This leaves employers to come up with new strategies for hiring Python developers.

If you are among them, here’s a detailed checklist that will help you verify whether the candidates fit your profile. 

1. Define Needs Before Hiring Python Developers

Python Programmers’ jobs are surging. Tech teams are pressuring the HR teams to hire python programmers with better skills and experience. But as a hiring member, don’t be in a rush. Before you post the ‘We are hiring Python Developers!’ advertisement it’s essential to work on the prerequisites.

Python is an excellent language with its use cases across different verticals. Hiring a dedicated python developer will help you in developing robust Python solutions. But before hiring python developers, you must have clear ideas of what achievements you want to conquer. Do you want to build a website or a game? Do you want to hire freelance python developers or hire a python development company

You will have to follow a different process based on your requirements. For example, you can’t ask machine learning or data science interview questions to a freelance python web developer. These are some minute yet important things you must look out for before proceeding to hire python developers. 


You’ll often struggle to identify what you need. So don’t be in a rush and hire someone who is incompetent. Take your time,  have a clear understanding of what you need and narrow down your focus to hiring python experts with the necessary knowledge and experience.

2. Assess Candidates Through Aptitude and Technical Tests (If You Require Freshers)


If you are hiring Python programmers, an aptitude and a technical test is a must to measure the calibre of applicants. You must work with your technical teams to compile Python interview questions. You may divide the test into three parts: aptitude, verbal and logical, and technical. These tests will measure the strengths and weaknesses of python developers, communication skills and technical problem-solving skills. 

3. How to Interview Before Hiring Python Developers

Before finalising your dedicated Python developers conduct interviews and interact with them.  Try to grasp their understanding of technologies, their intuition and how they solve complex problems.

3.1 Assess the Technical Part

3.1.1 Tech Stack

A tech stack is the technical set of tools, libraries, frameworks, and programming languages that help build a project. 

Based on your requirements python tech stack will vary. If you want to hire python web developers, your tech stack will include:

  • > Front-End Development: HTML, CSS, JavaScript
  • > Backend Development: Apache Web Server, MySQL Database.

These can be powered by the Python-Django Tech stack to build your robust web application. 

Accordingly, these tech stacks will change if you want to hire python engineers for game development or ML/AI development. 

Based on your requirements, ask the candidate if they are fluent with the tech stack. If not you can quickly go to the next candidate. 

3.1.2 Experience Level

Experience level of the Python expert is an important factor.  Ask the candidate about his work experience and what type of project he has worked on previously.

This makes it easy for you to understand how that candidate can handle complex projects. Moreover, you will get insights into how he worked on that project and his problem-solving skills.

3.1.3 Domain Expertise

You must hire Python developers who have up-to-date knowledge of the Python ecosystem, its libraries and frameworks.

While you interview your future python developers ask questions regarding their domain expertise.

For example, if it’s a Python web developer, ask questions regarding the front-end part (page layout, implementation of user interface, and SEO optimizations) and the backend part (execution logic, database, API, security protocols, cloud platforms, and containerization).

If you are hiring Python machine learning experts, you can ask questions on regression, classification, supervised and unsupervised machine learning, different types of clustering, etc.

3.1.4 Flexibility to Shift Between Technologies 

You must not hire Python developers with expertise in a particular domain. It is not easy to find versatile python developers. But you must not lose hope. Even if the python developers do not possess working knowledge from different verticals, he/she must show positivity and willingness to learn when the time comes.

To solve the issue, ask the candidate what technologies he can work on and if he will be willing to change his learning direction. For instance, you can ask Python web developers whether they would like to do machine learning, data science, or AI.

From this, you will find if your prospective python developers are versatile or not. It will be a big win-win situation for as well as the developer. Always keep your eyes open to find such talent. 

4. Test Programming and Problem Solving Skills


Test Programming and Problem Solving Skills - Optymize

Before hiring Python developers, you must test their programming and problem-solving skills. You can use test projects to quickly assess candidates’ knowledge and ability to solve problems. Work with your python development team to assess the candidates’ working styles and thinking processes.

Some factors on how you can measure the python developers’ bright skills are: 

  • > Check how many test cases the candidates successfully complete.
  • > If candidates succeed, ask for other ways to solve the same problems. From this, you can measure his critical thinking capabilities.
  • > Evaluate the time taken by candidates to come up with a solution.

5. Verify Whether The Candidates Stay Up to Market Trends

Hire Python experts with robust coding skills. Period. But to advance your projects, you should make sure that the candidates stay up to the market trends.

One way you can do this is by visiting the candidates’ GitHub profiles to check their  development, testing, and open-source activities on the platform. After that, you can conclude whether the candidate is a tech enthusiast or contributes to the open-source community and has a passion to keep updating his old projects with new technologies.

6.Check Other Qualities 

Soft and interpersonal skills are equally important, so check if the candidate possesses the following qualities:

  • > Interest in building challenging applications.
  • > Professional mindset.
  • > Great enthusiasm.
  • > Social skills.
  • > Excellent communication skills.
  • > Proficient English speaker.
  • > Honesty.
  • > Curiosity.
  • > Flexibility.

Python is a dynamically typed language. What do you mean by that?


In Python, variable types are not explicitly declared, and can change dynamically during runtime based on their assigned value.

What is the difference between a list and a tuple in Python?


A list is mutable, meaning it can be modified, while a tuple is immutable and cannot be changed once created.

What is the purpose of virtual environments in Python?


Virtual environments allow developers to create isolated Python environments with specific packages and dependencies, avoiding version conflicts and ensuring reproducibility.

What is a decorator in Python?


A decorator is a function that takes another function and extends its functionality without modifying the original code. Decorators are often used for logging, authentication, and other cross-cutting concerns.

How is memory managed in Python?


Python uses automatic memory management, known as garbage collection. Objects that are no longer referenced are automatically deleted from memory.

What is the difference between the range() and xrange() functions in Python 2.x?


range() returns a list of numbers, while xrange() returns an iterator that generates the numbers on the fly, saving memory and improving performance. In Python 3.x, range() behaves like xrange() and returns an iterator.
