Hey folks! I've been a backend developer for about 3 years, mainly working with Java and the Spring Boot framework. Recently, I've received a job offer that uses .NET with C#. I'm excited about learning new technologies, but I'm also thinking about how this decision will impact my career in the long run. If I take the job and work with .NET for the next 3 years, I'll end up with 6 years of backend experience total—3 in Java/Spring and 3 in .NET. I'm concerned about how future hiring managers will perceive this split experience. Will it make me look less senior in either technology? Might I risk becoming a generalist without expertise in one specific area? On the flip side, could having knowledge in two different stacks actually be advantageous? Here's what I'm curious about: 1. For those who switched between Java and .NET, how did it affect your career? 2. What's the perspective of hiring managers on varied tech experience? 3. Is it better in the long run to specialize in one stack, like becoming really senior in Java/Spring, instead of diversifying into another like .NET? Thanks for any insights!

Years ago, I picked Unix over Windows and later transitioned to Java and Spring. Throughout my career, I've always found opportunities available. Personally, I lean towards specializing in one stack, but either choice can be suitable depending on your local job market.
Java and C# are really similar languages, so I think you’ll be just fine. What hiring managers really care about is whether you know your stuff, not necessarily the specific languages you've used. I made a successful switch to a senior C# .NET role despite having no prior experience in .NET, and it was my Java background that got me in the door.
Taking the .NET job means you’ll gain more experience across different languages, which is a plus. You definitely don’t want to be the developer who avoids learning new technologies.
I believe switching will actually enhance your credentials. While the syntax is similar, each environment has its unique features and challenges. Understanding both Java and .NET can only work in your favor in the job market.
I've seen hiring managers react in different ways: some think it’s not a big deal at all, while others can be really picky about sticking to the latest tech stack. If you're worried, it might be safer to focus on one area, but it's definitely possible to do both.
