Welcome to Cracking the Python Interview
This course is from a software engineer who has managed to crack interviews in around 16 software companies.
Sometimes, life gives us no time to prepare, There are emergency times where in we have to buck up our guts and start bringing the situations under our control rather then being in the control of the situation. At the end of the day, All leave this earth empty handed. But given a situation, we should live up or fight up in such a way that the whole action sequence should make us proud and be giving us goosebumps when we think about it right after 10 years.
This course covers all python programming interview questions extensively and will help you to crack all python interviews related to programming
This course will help you to crack python interviews to get your next python automation or development job. This course will teach you how to utilize your python programming skills in your next role as a python automation engineer and developer.
Anybody who completes this course, in a mere 12 to 13 hours of journey in this course, he or she will able to gain up to 3 years of experience in python coding
The problem faced by most them is it is difficult for them to clear python automation or development interviews. Because in interviews, all can answer questions expecting one line answers in python. But most of them lose confidence when they are asked to write programs during interviews. Taking up this course will help you to develop and boost your programming skills especially during interviews. Understanding and learning every program here in this course will give you a lot of confidence to face the interviewer.
Sometimes, Even though people manage to clear the interviews, due to poor programming skills, it is difficult for them to survive in the organization. This course comes in handy during this situation. Apart from helping the students to clear the interviews, this course puts in great effort to explain each and every program in the course. Each and every line in these programs are explained to much greater depths.
This course covers the following:
Advanced and Basic Python Interview questions on Programming
Unit and Api Testing Module in Python
Static Code Analyzer Tool for Python
Code Coverage Tool for Python
Course on How to sell yourself in Automation Face to Face Interviews (This has Tips, Tricks and Project ideas to clear Automation Interviews. This involves 10 Face to Face Interview case studies of Automation Interviews )
