(Yuliana): When interviewing, I had a problem or, better to say, many problems with my self-perception and self-confidence. I believed I didn't deserve a better role, a better company, a better salary. I was very modest and always straightforward in my expectations that I communicated to recruiters. When recruiters asked my salary expectations, I answered with a smaller range because I was too afraid to get a refusal straightaway. I didn't know how to negotiate at all. Moreover, I just believed my expertise was not worth negotiating a better deal.

Fortunately, I had the right people around me, who pointed at my impostor syndrome. It took me a few months until I accepted and learned how to deal with it. It's interesting that once I realized what I was capable of, it took me only two days to build a decent portfolio website showcasing my work and experience.

Developing self-confidence requires lots of work. It's not something you can gain in a few days. You need time to accept it, and you need to practice it to accumulate it. Below is a list of 10 resources that helped me overcome my fears and start seeing myself from a different perspective. Please don't take it as a holy grail. These books and one video mini-course can't bring self-confidence to you, but they show you things from a different perspective and make you start thinking differently.

The first five resources I specifically pre-selected and read/watched at the time when I was preparing for the onsite interviews:

1. Lean In: Women, Work, and the Will to Lead by Sheryl Sandberg.
2. Pitching Yourself by Jodi Glickman
3. The Power of Vulnerability: Teachings of Authenticity, Connection, and Courage by Brené Brown
4. Quiet: The Power of Introverts in a World That Can't Stop Talking by Susan Cain
5. You Are a Badass: How to Stop Doubting Your Greatness and Start Living an Awesome Life by Jen Sincero

The second five books I read before I started looking for a new role, but I highly recommend them because they positively impacted my self-perception too:

6. Extreme Ownership: How U.S. Navy SEALs Lead and Win by Jocko Willink and Leif Babin
7. So Good They Can't Ignore You by Cal Newport
8. Barking up the Wrong Tree: The Surprising Science Behind Why Everything You Know About Success Is (Mostly) Wrong by Eric Barker
9. The Subtle Art of Not Giving a F*ck: A Counterintuitive Approach to Living a Good Life by Mark Manson
10. Becoming by Michelle Obama

It's funny, but on my first day at Google, I learned that every Noogler when joining Google experiences impostor syndrome in the first few weeks or even months. It's absolutely okay. Just embrace it and learn to deal with it.
