Hi everyone, In this article, I going to share the path I followed to become a java developer. I know that as a beginner one didn’t know how to become a software developer and be placed in a good company. The resources that I am going to link in this article are also free of cost.
1. Learn Java
The first step in the process is to learn java. There are various courses on the internet to learn java, but the efficient way to learn any programming language is by practicing while learning. I learned java from Sololearn.com and codecademy.com. These two websites have hands-on practice sessions in a structured pattern. Sololearn’s website also provides you with a certificate on completion of the course.
2. Data structures and algorithms
After you become familiar with all the basics and OOPS concepts of java. The next step is to learn Data structures and algorithms. It helps in understanding the nature of the problem at a deeper level. The topics that you should cover are stack, queue, bag, union-find, priority queue, quicksort, mergesort, heapsort, BST, red-black BST, hash table, BFS, DFS, Prim, Kruskal, Dijkstra, radix sorts, tries, KMP, regexp, data compression, B-tree, suffix array and maxflow.
Algorithms-Part1 and Algorithms-Part2 are the two highly recommended courses from Coursera that I suggest you go through. Also, this course is free to access.
3. Interview preparation
The next step after you become good at data structures and algorithms, you should start your interview preparation. The mistake that everybody does is they apply for job posts right after they learned a particular language and some concepts. Interview preparation plays a vital role to be hired by a reputed company. One should spend at least one month preparing for the interview.
In my opinion, Leetcode is the best platform to practice quality interview questions for free. The problems are divided into three categories namely easy, medium, and difficult. If you are able to complete medium-level problems within 45 minutes, then you are ready to give interviews in any of the product-based companies.
4. Resume building
Resume building and interview preparation should go side by side. According to me, a good-looking resume should be within a page. The projects you add to your resume really matter. Start building small projects while learning. Participate in more hackathons and do consider adding your achievements to your resume. Refer to the following links for more project ideas and resume templates.
