There are many ways to find an internship. Searching can oftentimes be intimidating and this can oftentimes lead to feeling frustrated or giving up. Stay focused on the types of opportunities you want to gain.
What type of internship will benefit you the most? This internship may help you develop technical knowledge (hard skills) or it may help you develop into a professional (soft skills). This will help you narrow down the scope of the internship.
Do you have a specific company or organization you want to work for? If this is the case you will need to research what their application process looks like and if you have any connections.
