Do you really need it? - In disciplines like technology you do not need to have a Ph.D. to become the best. Since this is a practice-based industry, you can gain relevant skills while working in the field.
Research your area of interest - Once you have decided to jump aboard the Ph.D. boat, research your area of interest
Project-based Ph.D. v open Ph.D. - Generally, you can choose any topic of your interest after getting into a Ph.D. or even during the application itself.
Choosing a supervisor - A good supervisor during your Ph.D. is crucial. You will need them to guide you in the right direction academically.
Should you choose an interdisciplinary topic? - There is a lot of freedom in choosing your Ph.D. topic and it can end up becoming very specialized, but try to think about the employability factor as well.
Be a reader - A Ph.D. aim to create an independent and keen scholar, and for that, it requires someone who can sustain wider reading.
Academic life and networking - Network with colleagues, researchers, and academics, and develop your networking to balance the inherent solitude of research life.
Passion and commitment - Don’t just do a Ph.D. to add “Dr” before your name or for any kind of recognition. The main reason to do a Ph.D. is to study a topic in-depth.
Take a gap year but don’t let it run on - Do not wait too long before starting your Ph.D. if you want to be in academia. It will really hinder your career enhancement.
