12 String coding problems for QA Automation Interviews

Hi Reader, Hope you’re doing well! So far, we’ve covered Numbers, Loops, and Arrays in previous articles. Now it’s time to move to one of the most important topics for QA automation interviews - Strings. In real projects, you constantly work with text data: Usernames and passwords API responses Error messages Validation messages Logs That’s why strong string-handling skills are essential for any QA engineer who wants to move into automation. Below are 12 string coding problems arranged from...

Hi Reader, Hope you’re doing well! Last week, I shared 22 basic coding problems on Numbers and Loops. If you’ve been practicing them, that’s awesome. If not, don’t worry - take it at your own pace. The goal is to understand the logic, not rush through. Now, if you’re comfortable with loops, it’s time to level up a bit: Arrays. Arrays help you move from working with single numbers to handling multiple values at once. This is exactly the kind of thinking that comes up in QA automation...

Hi Reader, Good day, hope you're doing well. If you an QA Engineer who is beginner in coding, practice the below 22 coding problems on Basics - Numbers and Conditions, Loops. There are further topics on Arrays, String, Collections which I will share in another email. You can search for solutions on YouTube, Google, ChatGPT, Gemini tools. The focus should be on practice in Coding Editor (Eclipse IDE or IntelliJ) and understanding the logic, not memorizing the actual code. During Interviews how...

Hi Reader, Happy New Year 2026. I am probably late to share the New Year wishes to the folks on my email newsletter, today I got some free time being a holiday. I will try to write more often in 2026, once or twice a week. One QA engineer replied to my welcome email and said: “I need to learn how to find correct and different use cases from the requirement.” Honestly, this is something almost every QA engineer struggles with at some point. Not because testing is hard.But because requirements...

Hey Reader, I got a question about test coverage recently, so I thought to draft this email. When you hear “test coverage,” what pops into your head? Most testers think: “How many test cases have I covered?” And honestly, that’s not wrong. But it’s also not the full picture. Test coverage isn’t really about the number of tests. It’s about confidence - how sure you are that the important stuff won’t break. So, let’s break it down. Thinking broadly - that’s about asking: “What all could break...

Hi Reader, Hope you're doing well. Over the years, I’ve noticed something interesting in Testing careers. People don’t suddenly become Test Architects.They slowly start thinking differently, often long before the title appears. This isn’t a checklist or a certification path. It’s a shift in mindset and responsibility. If you’re early in your QA career, don’t try to jump ahead. Just notice how thinking evolves as responsibility grows. That awareness itself is a strong start. Here’s how I’ve...

Hi Reader, Hope you're doing well. I often get questions about how to grow as a QA engineer - here are two stories that might give you some perspective. I had a couple of conversations with QA engineers this month, and I wanted to share them - they reminded me why small, consistent practice matters. One was a Senior QA Lead with 13 years of experience. He’s experienced in testing and managing teams, but he hardly touches code these days. He wants to move into more technical roles, but without...

Hi Reader, Hope you're having a good day! This email would be helpful for Folks in India. QA Engineers in other countries as well can get high level insights about the Job Descriptions for Automation Test Engineer roles. I understand that many folks are looking for job opportunities, and I had observed EPAM is conducting multiple Face to Face drives across India for Automation Testing - different programming languages (Java, .Net, Python, Javascript). If this is suitable go ahead to apply and...

Hi Reader, Hope you're having a good day! For a Software Test Engineer just getting in the IT industry, many people simply say Software Testing role is low paying job. Don't take the opportunity, look for developer jobs etc. In 2025, getting Job into Software Engineer role could be tougher than earlier due to intense competition. Also experienced Software Engineers should not leave their current jobs without proper preparation. If you got an opportunity initially in the career, the role that...

Hi Reader, Hope you're having a good day! Many folks usually reach out to me, asking I often forget and not able to focus on learning. In 2025, it is not lack of learning resources or roadmap, but there are lot of distractions. Low attention span with social media scrolling for many hours daily watching short form content. Also, poor sleep affects the focus level, as we spend more time watching OTT (movies, web series etc.) late nights and we do not get enough sleep regularly. Try to fix the...
