Companies don’t invest in Liabilities

This course demands 8 weeks, 24-30 days, 12-15 hours every week of your life to invest for your career that isn’t a big deal. Huhh? Right. 30 days of preparation and be in a better position to bargain for a handsome salary is far better than going for an interview without practicing, placing at a low salary position for few years, bearing every-day stress for reaching to next level in your dreamy tech firms. We will help you in proving yourself as a valuable asset for the company, rather than an unpolished unskilled liability.

Where to Start?

Today a bundle of good websites, reading material, hands-on coding practicing platforms available at your one touch. Where to Start? This course is an ultimate platform for you and your fellows to start with. Live-interactive sessions, Leet Code of 30 days Challenge- practicing with global programmers, 24/7- 2 months feedback from instructors will prepare you for your next job interview at top-tech firms.

Learn in-depth technical skills to crack placement procedures in our 1-week Mock Interview Sessions with hiring experts of Software Houses.
