Which programming language should I use on interview?
Companies usually let you choose, in which case you should use your most comfortable language. If you know a bunch of languages, prefer one that lets you express more with fewer characters and fewer lines of code, like Python or Ruby. It keeps your whiteboard cleaner.
Try to stick with the same language for the whole interview, but sometimes you might want to switch languages for a question. E.g., processing a file line by line will be far easier in Python than in C++.
Sometimes, though, your interviewer will do this thing where they have a pet question that’s, for example, C-specific. If you list C on your resume, they’ll ask it.
So keep that in mind! If you’re not confident with a language, make that clear on your resume. Put your less-strong languages under a header like ‘Working Knowledge.’

Polymorphism in Java
📍 Polymorphism allows a single interface to be used for different types of actions.
📍 It is of two types:
Method Overloading (Compile-time Polymorphism)
Method Overriding (Runtime Polymorphism)
Method Overloading (Same method name, different parameters)
class MathOperations {
int add(int a, int b) {
return a + b;
}
double add(double a, double b) {
return a + b;
}
}
Method Overriding (Same method in parent and child class)
class Animal {
void makeSound() {
System.out.println("Animal makes a sound");
}
}
class Dog extends Animal {
void makeSound() {
System.out.println("Dog barks");
}
}

Working under a bad tech lead can slow you down in your career, even if you are the most talented
Here’s what you should do if you're stuck with a bad tech lead:
Ineffective Tech Lead:
- downplays the contributions of their team
- creates deadlines without talking to the team
- views team members as a tool to build and code
- doesn’t trust their team members to do their jobs
- gives no space or opportunities for personal / skill development
Effective Tech lead:
- sets a clear vision and direction
- communicates with the team & sets realistic goals
- empowers you to make decisions and take ownership
- inspires and helps you achieve your career milestones
- always looks to add value by sharing their knowledge and coaching
I've always grown the most when I've worked with the latter.
But I also have experience working with the former.
If you are in a team with a bad tech lead, it’s tough, I understand.
Here’s what you can do:
➥don’t waste your energy worrying about them
➥focus on your growth and what you can do in the environment
➥focus and try to fill the gap your lead has created by their behaviors
➥talk to your manager and share how you're feeling rather than complain about the lead
➥try and understand why they are behaving the way they behave, what’s important for them
And the most important:
Don’t get sucked into this behavior and become like one!
You will face both types of people in your career:
Some will teach you how to do things, and others will teach you how not to do things!
