Everyone's experience will be different, I would suggest using all of the resources available to you to assist in this process. Does your school have some sort of career for professional development center? This can assist in polishing your resume, interviewing, and delivery of your personal pitch. Otherwise, perhaps there is an office of alumni relations? This could connect to openings at alumni companies. Do you have a strong network? Utilizing your connections can have an impact on recommendations for positions. Perhaps it's not someone in your immediate network, they may have people in their network they could connect you with.
Best of luck.
