Apple exec's advice for gaining confidence in a new job: "Feeling insecure is normal, but don't let it hold you back."

Angela Ahrendts, who spent over two decades in the fashion industry, including eight years at luxury brand Burberry, decided to transition into the tech sector.

In 2016, she joined the Apple executive team as senior vice president of retail and online stores.

Ahrendts stated at the World Business Forum in New York City that the jump was not the most comfortable.

"In the initial month, you experience insecurity and become overwhelmed due to focusing on what you don't know."

Ahrendts came to the conclusion that she was not hired to possess more knowledge or be as knowledgeable as other employees at Apple. Instead, she was hired to contribute something unique and distinct to the company that others couldn't provide.

She stated that it was not her responsibility to know, but rather to connect and enable. Her role was to create a new framework and bring people together.

Starting a new job in a different industry can make you feel overwhelmed and inadequate, but there are ways to overcome imposter syndrome and negative self-talk.

Question your thoughts

Judy Ho, a neuropsychologist and professor at Pepperdine University, advised CNBC Make It to be aware of the triggers that lead to negative thoughts about one's abilities.

Ho stated, "Take note of the patterns and triggers that arise in certain situations, and you will begin to discern a theme."

What evidence supports the idea that you are incapable of doing this specific job, and what evidence contradicts it?

Evidence shows that you bring a lot to the table, Ho said.

This exercise can also help you remember that these thoughts aren't fact.

"Ho stated that thoughts are not absolute truths, as there is no way to have tens of thousands of thoughts and for all of them to be true."

Criticizing the stories you tell yourself can help alleviate any anxieties you may have about being new in the workplace.
