There are multiple job portals that you can refer while searching for an internship position. Few of the popular ones are as listed below. Keep in mind to apply as soon as the job posting is put up. Additionally, you can search in the career section of companies and apply to their open positions.
It is recommended to maintain an Excel sheet where you put the information about the position and company applied, date and the status. It helps to track the application and contact the HR if there is no feedback for over more than 4 weeks. Also remember to save the job advertisement and HR contact details.
