There are many other companies in the field looking for software engineers. Be sure to turn on your job alert in LinkedIn and check sites like Glassdoor frequently.

Recruiting

Software engineering internship and new grad recruiting typically start around late August/early September, and last until January/February of the following year, with some jobs still open in March or April.

The first step in a software engineering application is to submit an online application with your resume and (sometimes) portfolio. Be sure to do personal projects or participate in hackathons to fill out your portfolio. After the application is received, most companies will send you a coding challenge. These are timed challenges with basic to intermediate coding problems meant to test a candidate's basic competency. If you pass the coding challenge, the final step in the process is to participate in 1 or more rounds of interviews. These interviews are typically conducted by an engineer at the company, and you could be asked to write code on a whiteboard or even make fully functional software.
