To gain confidence in writing programs, it’s important to work on yourself via online courses or platforms such as Code Institute. By following these tips, you will be well-prepared for your Python interview and have a better chance of impressing the interviewer and landing the job. Be prepared to ask questions and demonstrate your interest in the company and the role.
- For data engineer roles, the gap narrows somewhat — performance, memory management, and pipeline design become shared territory.
- I’ll walk you through each question with clear explanations and concise answers, presented in a conversational format between an interviewer and an ideal candidate.
- Numerous database-related modules are available in Python, making it simple to communicate with a wide range of database systems from within the language.
- How you approach error handling tells interviewers a lot about whether you’ve worked with production code before.
Whether you’re applying as a fresher or an experienced professional, the selection process is designed to evaluate technical knowledge, problem-solving abilities, and communication skills. With a strong focus on digital transformation and enterprise solutions, Infosys regularly recruits skilled developers proficient in Python, one of the most widely used programming languages today.

I would validate incremental extraction using timestamps or keys, verify transformation rules, and perform end-to-end testing to ensure no duplicate or missing records exist in the target system. In ETL (Extract, Transform, Load) operations, a https://uvik.io/ lookup is a process used to retrieve a specific value or an entire dataset based on input parameters.
They both provide you the option of generating a list of integers to use whatever you want. When a module is imported, PYTHONPATH is checked to see if the imported modules are present in various folders. For instance, in Python, the variables “myVar” and “myvar” are regarded as distinct entities, and using them in the incorrect case can result in coding mistakes. Function overloading is the capacity to define many functions with the same name but different argument lists.
Additionally, there were two coding questions included in the assessment, with difficulty levels ranging from easy to medium. The online test consisted of multiple-choice questions (MCQs) covering aptitude, Spring framework, Angular, and data structures. Explain how to benchmark and optimise data-frame joins in Polars versus pandas, including Arrow memory layout considerations.
KORE1’s own placement data across our IT staffing services practice shows Python searches have increased roughly 40% year over year since 2024, and the qualified candidate pool has not kept pace. Python-specific roles are growing faster than that baseline because they sit at the intersection of backend development and the AI boom. We earn a fee when companies hire through us, so factor that into what follows. I’m a partner at KORE1, and our Python developer staffing practice sits across AI, backend, and data teams in 30+ U.S. metros.
