Python Coding Interview Tips
Standing out in your Python coding interview requires a consistent and well-thought-out strategy. FAANG+ companies have extremely low acceptance rates, making it significantly tricky even for experienced programmers to land offers. To answer tough Python coding interview questions, you must remember to practice coding problems every day and diligently work towards mastering problem-solving.
In this section, we’ll look at some practical tips that will help you stand out in your Next Python coding interview.
Choose the Right Built-in Functions While Solving Problems
Python interviews aren’t just about finding the solution to a problem. They’re more about your approach to writing error-free prolific problem code. They’re about how you can use Python’s built-in libraries and functions to find the optimal solution to a problem.
Compared to the standard library, Python has a relatively short built-in library, but the functions are readily available, meaning that you don’t have to import them. Let’s look at some readily-available built-in functions and how to use them to stand out in your Python coding interview.
One of the best ways to stand out in your Python coding interview is to use the proper built-in functions and leverage Python’s resourceful libraries. Let’s look at how you can do this and stand out in your next Python coding interview.
Debugging with breakpoint() instead of print()
Using the print() function to debug your code will make the code longer and more difficult to read and execute, consuming more time and memory. Using the breakpoint() function will make your debugging process much quicker and smoother.
Using f-strings to format strings in Python
Python has multiple procedures to format strings. This can sometimes create confusion around which particular formatting procedure to employ. F-strings in Python makes it easy to format strings, especially if you’re coding in version 3.6 and above.
Executing iterations with the enumerate() function instead of the range() function
Iterations are situations when a certain set of instructions need to be executed repeatedly before a result is obtained. While running iterations, it makes sense to use the enumerate() function, especially if you wish to iterate list items from their index, as the enumerate() function works much faster than the range() function.
Using sorted() to sort complex linked lists in Python
This is applicable when you solve problems on linked lists. Unless you’re building your one sorting algorithm, using sorted() makes a ton of sense while tackling linked list-related sorting problems in your Python coding interview.
Use Generators Against List Comprehensions
Using list comprehensions works if the size of the list is minimal. Using list comprehensions to execute code blocks consumes way more time and memory for larger lists. Therefore, using constructors is the best way to approach problems that pertain to lists.
Using Python’s Collection Module
The best way to implement Python’s container data types, such as tuples, sets, lists, dicts, etc., is through the collection module. Employing the collection module for these container data types - UserString, Counter, OrderedDict, Chainmap, ChainMap, UserList, and namedtuple() can largely influence the performance of your program.
The **kwargs Function
The ** kwargs keyword defines functions that pass argument lists of variable lengths. With this, you don’t need to determine the length of a particular argument list, making it much simpler and more effective while passing arguments.
Master Core Data Structures and Algorithms
Your ability to solve challenging problems in core data structures and algorithms vastly influences your interview success. Interviewers typically want to understand your approach to problem-solving and how effectively you can articulate your thoughts. As such, mastering the fundamental concepts in core data structures and algorithms is key to standing out in your Python coding interview.
Understand the Working of Different Python Tools
Knowing how various Python tools work should be an integral part of your prep strategy. Tools like Theano, SciPy, Robot Framework, Test Complete, and Scrapy are popular tools developers are expected to know. Spend time learning how some of these tools work to get ahead of your competition.
Practice at Least 1-2 Coding Problems Everyday
Diligent practice is the only proven way to sharpen your problem-solving skills. While prepping for coding interviews, begin your prep at least ten weeks before getting ample time to cover all the essential topics. Practicing at least 1-2 coding problems every day is highly recommended to take your problem-solving skills to the next level. Because eventually, it is your approach to problem-solving that will be decisive.
Identify Patterns in Problems to Boost Your Problem-Solving Skills
In continuation to the previous point, the best way to give your problem-solving skills a boost is by identifying inherent patterns in solution patterns while solving problems. When you solve problems, aim to figure out what problems have similar solution patterns and classify them accordingly.
By doing this, you’ll be able to solve new problems by using analogous problems. Identifying patterns and using these power patterns to solve problems is the quickest and most effective way to boost your problem-solving skills.
Do Timed Tests and Practice Whiteboard Coding
On-site interviews at FAANG+ companies can sometimes test your ability to code on a whiteboard. The idea behind this is that it makes it possible for recruiters to gauge your thought process and problem-solving approach and consequently make a hiring decision.
Timed tests are another way to gear up for your interview. By exposing yourself frequently to an interview environment, you will be able to perform better when the real test transpires.
Practice Mock Interviews
Mock interviews are the best way to hone your interviewing skills. They help you build confidence, overcome interview anxiety, and also help you understand what to expect at coding interviews.
By practicing mocks with professionals who can give you the proper feedback, you can take your interviewing skills to the next level, stand out from the crowd, and make a great impression.
Create a Strong Portfolio
A strong portfolio can greatly influence interview success. Make sure to spend time listing out the important projects you worked on. List them in the STAR format to give interviewers a clear understanding of the events around the project.
