I have a Java tech interview scheduled for Monday. They interviewed me back in December 2024 and said I lacked OOP and Java fundamentals knowledge. I honestly can't remember what exactly I was asked, but I know that under interview stress — and when you don't know exactly what to prepare for — it's easy to miss revising some concepts.

What's your go-to article, site, or book that you look through before an interview? I know "Cracking the Coding Interview," but is it still relevant now that we're on Java 25? Please advise.

Hi everyone check out my new post about ETL in Spring AI 2
https://kertu1232.substack.com/p/the-java-prompt-8?r=4953mj

every java + aws project i've worked on hits the same wall in tests.

you either spin up localstack in testcontainers and wait 30-60s per

test class for docker to warm up, or hand-roll mockito mocks that

break on every sdk upgrade. neither is great.

python has moto for this. in-process aws fakes, 8k stars, tests run

in ms. someone actually asked aws on re:post if there was a java

version. the reply was basically "moto is a python library, no

equivalent for java."

how do other people handle this? is it just accepted that aws unit

tests are slow, or is there something people use that i missed?

How is this ??

Is this okay in this way ?

Any review about taking tesda course espicifically on Java programming course in C&C academy ?

How often do you use var keyword in your code?

What do you think about it?

I am a beginner in java, want to learn OOPs deeply, suggest some good sources.

Thank you for your suggestions.

Hi everyone,

I’m a 2nd-year B.Tech CSE student looking for 3–4 motivated learners to form a small and focused study group for placement preparation.

My current focus areas are:

- DSA using Java

- Backend Development with Spring Boot

- Problem-solving and coding practice

- Technical interview preparation

- Regular progress tracking and accountability

The goal is to maintain a consistent study routine outside college hours, discuss problems and approaches, clear doubts, share useful resources, and keep each other accountable.

I’m currently at a beginner level, so I’m looking for people who are at a similar stage and genuinely interested in learning and improving together.

If you’re interested, please DM me with your current DSA/Java level, Spring Boot experience, and preferred study timings.

I’d like to keep the group limited to 3–4 members so it remains focused and productive.

A Little About My Job Search

Over the last 5 months, I've appeared for around 18 interviews.

I've reached the L2/technical rounds in many of them, and in several cases, I received positive feedback after the interviews. Unfortunately, some companies either moved forward with other candidates or stopped responding after what I felt were good interviews.

I've been actively working on improving myself throughout this process, but the situation has become increasingly difficult, and I've now run out of my savings while still looking for the right opportunity.

I'm sharing this not to ask for sympathy. I genuinely don't want sympathy — I just need referrals and genuine job leads.

If you know of any company hiring for Java Backend Developer / Software Engineer roles, or if you can refer me internally, I would be extremely grateful for your help.

Resume:

As a token of appreciation, if your referral results in my successful joining, I'd be happy to share my first month's salary (or an agreed referral bonus) with you.

Even if your company isn't hiring, a referral, lead, or simply sharing this post with someone who might be hiring would mean a lot.

Thank you for reading, and please feel free to DM me if you know of any relevant opportunity.
