Focus on these 2 major areas:

1. Enhance Your Visibility: Visibility is an often underrated skill but crucial for standing out from the crowd. Participate in conferences, presentations, and online forums where you can gain and share knowledge. Visibility means actively engaging in activities that can be highlighted on your resume. Whether it’s presenting a paper, speaking at a conference, or contributing to a high-profile discussion, these activities make you more noticeable to potential employers.
2. Master Open Source Projects or Competitive Coding: To secure a dream job at top tech companies you need to excel in either open-source projects or competitive coding. There’s no room for mediocrity; aim for a perfect score. In competitive coding, strive to become a candidate master on platforms like Codeforces. If you choose the open-source route, aim to be selected for prestigious programs like Google Summer of Code (GSOC).

Mastery in these areas significantly boosts your chances of standing out in a highly competitive field. Let me know if you wish discuss these in detail over chat or a trial session.
