When you're studying DSA, you probably think, "This won't be directly used in the actual work of a company, so why am I even doing this?"
And in life, where will this even come in handy? Well, it won't be useful directly, but the hard work you're putting inβsitting day and night solving questionsβthat habit of working hard will pay off.
It's not really about DSA, but about the effort you're willing to give that will decide which company you land your internship or placement in β€οΈ

Essential programming language for Android app development ππ
1. Java: Java has been the traditional and most widely used programming language for Android app development. It is the official language for Android development and provides a robust set of tools and libraries for building Android apps.
2. Kotlin: Kotlin is a modern, concise, and expressive programming language that has gained popularity among Android developers. It is fully interoperable with Java and offers many features that make Android app development more efficient and less error-prone.
3. C++: While not as commonly used as Java or Kotlin, C++ can be used for developing performance-critical parts of an Android app, such as game engines or graphics-intensive applications.
4. Python: Although not typically used for building full-fledged Android apps, Python can be used for scripting, automation, and data processing tasks in Android development.
5. JavaScript: JavaScript can be used in combination with frameworks like React Native or NativeScript to build cross-platform mobile apps that run on both Android and iOS devices.
Overall, Java and Kotlin are the most essential programming languages for Android app development, with Kotlin gaining popularity as a more modern and efficient alternative to Java.

When you're studying DSA, you probably think, "This won't be directly used in the actual work of a company, so why am I even doing this?"
And in life, where will this even come in handy? Well, it won't be useful directly, but the hard work you're putting inβsitting day and night solving questionsβthat habit of working hard will pay off.
It's not really about DSA, but about the effort you're willing to give that will decide which company you land your internship or placement in β€οΈ

Preparing for an Interview?
Interviews can feel nerve-wracking, but with the right preparation, you can walk in feeling confident and ready to impress.
Hereβs a 10-step checklist to ensure you're all set:
πResearch the Company: Understand its values, culture, and recent news. This shows you're genuinely interested.
πKnow the Job Role: Be clear on the job description and how your skills match.
πPrepare Your Answers: Practice responses to common interview questions, like "Tell me about yourself" or "What are your strengths?"
πDress the Part: Choose professional attire that suits the company culture.
πBring Copies of Your Resume: Even if the interviewer has a copy, having one ready shows you're organized.
πKnow Your Resume Inside Out: Be ready to discuss your experiences, achievements, and gaps in your employment history.

Coding is tricky. Coding in interviews feels even harder. Itβs intimidating, uncertain and hard to prepare. Here are 4 ways to do it!
1. Interview Cake: I think it is some of the best prep available and it is targeted toward weaknesses many data scientists have in algorithms and data structures: https://www.interviewcake.com/
2. Leetcode: While developed for software engineering interviews, it has a LOT of useful content for learning algorithms. For data science, I'd suggest focusing on Easy/Medium: https://leetcode.com/
3. Cracking the Coding Interview: Amazing book, sometimes referred to as CTCI. A classic and one you should have: https://cin.ufpe.br/~fbma/Crack/Cracking%20the%20Coding%20Interview%20189%20Programming%20Questions%20and%20Solutions.pdf
4. Daily Coding Problem: The book and the website are awesome. Work on a daily problem. This was my go to resource for when I was looking to stay sharp: https://www.dailycodingproblem.com/
