Life offers an almost unlimited supply of chances to be rejected, and it is easy to take each one personally.

Picture a young man who works up the nerve to cross a room, tell a woman he finds her beautiful, and ask for her number. She says no, and he walks away believing she looked him over, weighed what she saw, and found it lacking.

That may not be what happened at all. She may have slept badly, or been running late, or just ended a relationship, or be seeing someone already. He may have reminded her of someone she can’t stand. She may simply not have wanted to meet anyone that afternoon. If he approached the same woman a year later and said nearly the same words, he might get a very different answer, and nothing about him would need to change for that to happen. The timing would be different, and so would her circumstances and priorities.

A rejection arrives as a yes or a no, which makes it feel like a clean judgment. The decision behind it is anything but clean. It is an equation with many variables, most of which you can’t see and many of which have nothing to do with you.

That is true of nearly every rejection you will face, whether it comes from an employer, an investor, a customer, an editor, or an admissions committee, and learning to read rejection accurately is a large part of what long-term success requires. Internships make a good example because they are where most people first meet rejection in large numbers, usually before they have learned how to interpret it.

What the rejections seem to say

You apply for an internship and get turned down. You apply for another and get turned down again. After twenty of these it is natural to conclude that nobody wants you, and after fifty that conclusion can harden into a belief that you just aren’t good enough.

Consider what is happening on the other side of those applications. For the student, landing an internship may be the most important thing in their life that year. For the company, filling it may sit somewhere around number 87 on someone’s list. Internships serve real purposes. They build a pipeline of future hires, give junior employees practice at mentoring, bring in fresh ideas, and let successful people and organizations give something back. They also cost time. Someone has to read the applications, run the interviews, scope a project an intern can actually finish, and answer that intern’s questions all summer.

So the person whose future seems to hang on the decision is often dealing with someone for whom that decision is one small part of a much larger job. That alone injects a great deal of randomness into the outcome, and it is only one variable among many.

Equally capable, different outcomes

Imagine two applicants who are, by any reasonable measure, equally capable. One lives ten minutes from the office and the other would have to move across the country. The local candidate gets the offer, and nobody involved has concluded that the other person is worse.

The two could also differ only in when they applied. One sends an application the week the posting goes up, and the other sends one a month later, after the hiring manager already has a shortlist and has stopped reading new applications closely. Applying early doesn’t settle the matter either, because the first applications can sit untouched until someone finds time for them, and whichever resume happens to be on top of the pile when the reviewer finally sits down gets the careful read. Neither applicant can see where they landed in that order, and the result says nothing about which of them is better.

Or imagine that one of two otherwise identical candidates spent more time on their resume. Instead of listing the name of a class project, they explain what they personally built, and their accomplishments are easy to follow. They get the interview even if they aren’t the stronger engineer, because they did a better job of showing what they had done.

Cover letters work the same way. Two letters can be equally well written while only one explains why this particular company interests the applicant and connects something the applicant has already done to the company’s work. That letter lands with the person reading it. Hand the same two letters to a different reader and the result could flip.

One candidate might figure out who leads the group they want to join, reach out on LinkedIn with a thoughtful question, and become a real person instead of another PDF in an applicant tracking system. Another might have an uncle who knows someone at the company and says, “You should at least talk to this kid.” Neither move guarantees anything, because the candidate still has to perform. But one application now gets ten minutes of attention while the other gets twenty seconds, and that difference can decide the outcome.

Differences that seem too small to matter

Suppose an aerospace company receives applications from two computer science students with similar grades, similar projects, and no prior internships. One of them happened to take private pilot ground school, and the hiring manager flies airplanes. It isn’t hard to guess which resume gets a second look.

The deciding detail could just as easily be a class project in computer vision when the group has an imaging project planned for the summer, or a university paper supervised by a professor the interviewer knows, or a personal project written in Rust at a company that builds in Rust. The hiring manager might have gone to UW and remember it fondly, or might hold an irrational grudge against it. People make these decisions, and people bring their interests, associations, biases, and moods along with them.

Sometimes the first filter isn’t the hiring manager at all. A recruiter works from a checklist an engineering manager handed over, without understanding the technology behind it. Your experience is relevant, but you described it in different terms, so you are screened out. Another candidate used the exact words on the checklist and gets an interview. That result says a lot about the screening process and very little about the relative potential of the two applicants.

The variables that belong to you

I keep the Serenity Prayer on my desk. Whatever you make of its religious framing, its central idea is practical. Learn to tell the things you can change from the things you can’t, and put your effort into the first group.

You have no say over who reviews your resume, how much time they have to spend on it, or where your application sits in the pile when they start reading. You can’t choose who else applies, including the CEO’s neighbor’s daughter. You can’t stop a company from losing a contract and freezing hiring the week before your interview, and you can’t pick where the hiring manager went to school.

You do have a say in whether your resume communicates clearly, and in whether you apply soon after a posting opens instead of the day before it closes. You can research the company and learn enough about its business to explain why you care about it. You can build things, write about what you built, and develop interests that make you worth talking to. You can contact people directly instead of relying entirely on an applicant tracking system, and you can ask family, professors, and friends whether anyone in their networks works in the fields that interest you.

You can also make it obvious that you have a direction. Compare a student who says, “I need an internship this summer,” with one who says, “I want to work on robotics and control systems. I’ve enjoyed building autonomous rovers in a campus club, I’m interested in how machines make decisions from sensor data, and I’d like to spend the summer somewhere I can see how those systems are built in the real world.” The second student may have no more experience than the first, but they have given the reader a reason to picture them inside the organization.

Rejection will still happen

You can do every one of those things well and still be turned down, sometimes over and over. You might apply to a hundred internships and hear no from ninety-nine of them, but you never needed a hundred internships. You needed one.

Those ninety-nine rejections don’t add up to a verdict on your worth. Each was a separate decision, produced by its own mix of timing, circumstance, competition, priorities, presentation, relationships, luck, and ability. Ability matters enormously over a career, but in any single decision it is just one of the variables.

A long run of rejections can still tell you something, because a few variables appear in every one of those decisions. Your resume, the roles you chose to pursue, and the way you describe your work went into all ninety-nine. When the same result keeps coming back, those shared variables are the first place to look, and they happen to be the ones you can change.

Internships are only the first place most people meet rejection in volume. Later it arrives as a job that goes to another candidate, an investor who passes on a pitch, a customer who picks a competitor, an editor who declines a manuscript, or a promotion that goes to a colleague. The equation is the same in each case, with many variables you can’t see, a few that travel with you, and a single yes or no at the end. People who build something meaningful usually collect far more rejections along the way than anyone else sees, and what distinguishes them is how they respond. They adjust the variables that belong to them and keep going, long after others have read the same results as a verdict and stopped.

My father likes to ask why God made men so stupid, and then he answers his own question. It was so they could do the impossible. He means the particular bravado of young men, which is often misplaced but sometimes useful. A young man who doesn’t appreciate how long his odds are will still cross the room, make the call, and send the application. Every so often that persistence pays off precisely because he never stopped to calculate how unlikely success was. As we get older, many of us get better at calculating the odds and worse at ignoring them. We start treating each rejection as a judgment about ourselves, and eventually as a reason to stop trying. Understanding what a rejection actually tells us lets us keep the persistence without depending on the ignorance.

Rejection will still hurt, because you wanted the thing you didn’t get. The useful response is a narrower question than “What is wrong with me?” Ask which variables in the equation belong to you, work on those, and then try again.
