Over the past 3 years, I've really put myself out there. At first, interviewing was a bit difficult. It had been a looong time since i've done any. It got easier with time. After a while, I stopped preparing for interviews and I started getting good at it (asking questions, finding out if that company is really good for you, answering questions about yourself, and of course passing the technical assessment (whether coding / algorithm interviews or even large-scale system design).

The only advice I can give (i've received a lot of good advice here) is to always interview. Always be up-to-date on the job market, with respect to skills, technologies, coding savviness, etc. Interviewing in the beginning may take a lot of your time, but if you do it consistently, it'll only helping you in future interviews. Don't be afraid of rejections, hell, even embrace rejections as a mean to get better in the future.

I was always afraid of having my skills eroded or even becoming obsolete as it got to a point where I was no longer learning new things on the job, so I had to push myself and make myself learn (most times on my own personal time). That's what pushed me to get out of my comfort zone, and do something that I know will be annoying and heck even make me scared.
