SubMastery stands for Subject + Mastery = SubMastery The growth comes with Subject Mastery, thus our tag line says - Growth with Subject Mastery We believe every engineer in our country needs respect and growth which they truly deserve. Somehow, in our present company culture, most companies management and HR professionals are less bothered about working engineers' learning and growth. They are just treated as machines whose No. 1 work is to give the best output but without time and effort in their training and mentoring by seniors. Good Boss vs Bad Boss The problem is with both of them. Nobody teaches our young working engineers in the companies. Good boss being busy doesn't have time to share his knowledge and the bad boss has a lot of insecurity and feels that if tell his juniors, he will lose his job! So, nobody is teaching the essential skills in the job to our young working engineers. Then, how they will grow and add real value to the companies? Like most engineers NOT aware of quality tools, management systems, auditing skills, core tools, etc. which are essential for them to know and apply in their career. The Problem The offline training if sometimes planned by company HR majority of the time does lack in the quality of trainers, no hand-holding, no assignments, no access to trainer after training, no access to best training material, cramming all information in a day or two :-( And if engineers want to attend the classroom training, the cost is very high and not affordable, they need to travel, need to apply leave and so many headaches to our young engineers. All the above factors act as negative and stop the learning and growth of these engineers. This results in engineers failing in the interview too often, not able to reply confidently to certification bodies, customers and company top management itself. No more trouble for engineers now Take the control of learning and growth in your own hands. Don't be dependent on your organization, HR, boss or colleagues for growth :-) To make learning real - one step ahead of certification, we at SubMastery is committed to the Growth of our engineer's community. This is done through intensive online courses with live classes, assignments, quiz, and test. We learn by doing. That's the reason you get to do the assignments which are reviewed by our competent quality coach. The video recordings are made available to you with multiple support for doubt clearing sessions through email, chat, dedicated community groups and live classes. Our Vision We are committed to help and get access to mentoring for 10 K engineers by the end of the year 2020 and create 500 transformational and success story. Our BIG vision is that every working engineering professional to get a mentor in their pocket (SubMastery: The Growth App) so that no doubt is un-answered and they make progress in their career, life, and family.
