2 Month Roadmap To Ace Any Tech Interview

-

 


When it comes to acing a coding/technical interview, there's nothing more important than having your tech skills sorted out. However, with so many things to study, it may be confusing to figure out exactly how to make your preparation as effective as possible. This article is aimed at helping you do exactly that.

So, what will we do in these 2 months?

Most interviews at top tech companies consist of the following:
1) DSA concepts
2) Core subjects
3) Coding and problem-solving skills

At times, the interviewer may also inquire about the projects on your resume (which is why you should be careful while writing this section of your resume - don't mention anything you are not confident in).

This post covers it all! Along with free resources of course :).

Master A Programming Language



Well, we can't have Software Engineering without a programming language. So, the first step would be to pick a programming language and STICK TO IT. Knowing multiple languages or the newest one in the market won't give you the upper hand - having mastery over any language, however, will.

Now, the question arises - which one should you choose? 
It doesn't matter, as long as you display proficiency.

However, make sure you are choosing a language that supports OOPs (Java, Python, C++, to name a few) as these languages often make coding much simpler with high-level functionality and huge libraries. You may also want to consider its applications.

Solidifying DSA Concepts



Data Structures and Algorithms is a must-know if you want to be a software developer. So, you must be thorough with these concepts.

Here is a list of topics:
  • Complexity Analysis
  • Arrays
  • Stacks
  • Queues
  • Trees
  • Tries
  • Linked Lists
  • Hash Tables
  • Graphs
  • Heaps
  • Sorting
  • Searching
  • Dynamic Programming
  • Backtracking
  • String Matching Algorithms
Below are some resources you can refer to.

Practice, Practice, Practice



As you start familiarizing yourself with DSA concepts, be sure to practice coding questions after completing a topic. Eventually, you will learn how to apply these concepts to solve problems (isn't that the goal?).

You can use multiple coding sites for this, like GeeksForGeeks, HackerRank, LeetCode, and many more.

Start with easier problems and slowly make your way up to the difficult ones. Be sure to understand different approaches to the problem as well, as your interviewer may ask you to solve a problem using a different technique than the one you have used.

Strengthen Your Core Subjects


Interviewers also test your knowledge of core Computer Science subjects. Some subjects that you should brush up on include:
  • Object-Oriented Paradigms (OOP)
  • Computer Networks (CN)
  • Operating Systems (OS)
  • Database Management Systems (DBMS)
Resources:

Know Your Projects



Building projects are the best way to test out your coding skills. However, be careful about which of these you put in your resume, as the interviewer may inquire regarding the same.

If they do decide to do so, you must be able to give satisfactory answers, and you should be able to explain to them anything that they wish to know about your project.

It is, therefore, a very good idea to take a look at your projects and ensure you know every little detail.

Some commonly asked questions about projects are:
  • Give me a summary of your project.
  • Why was this topic of interest to you?
  • How is this different from similar products in the market?
  • What tech stack did you use?
  • What challenges did you face while building this and how did you resolve them?
  • What are your biggest learnings?
  • How did you go about designing the codebase?
  • Which features would you like to add?

And That's It!

Now that you have it all laid out in front of you, what are you waiting for?
Go and ace that interview! All the best!!

During The Interview

Your qualifications and skills are part of what the hiring manager is looking for when conducting an interview. Whether you get the job also depends on how you behave at the interview—what you do, what you say, and how you say it. From the first door you walk through to the final handshake on your way out, this lesson will help you learn how to behave during an interview. Be punctual Being late for your scheduled interview can be an indication that you don’t pay attention to important details. It proves that you do not value others’ time. A lack of punctuality smacks of disrespect. That’s the last impression you want to leave interviewers with.  Plan to arrive on the scene about 10-15 minutes before the interview. This will allow you to sit quietly, collect your thoughts and allow yourself to be calm and focused on the interview. When you walk in, let whomever greets you know that you are a few minutes early.     Introduction Mention these four key pointers in your self introduction in
