Hello! So you’ve failed a handful of technical or behavioral interviews, and you’re trying to figure out what keeps going wrong.
This is a genuinely hard problem to diagnose, because the feedback you get from interviews is usually terrible. “We decided to move forward with other candidates” doesn’t tell you anything. You’re left guessing.
I’ve been thinking about this a lot, and I think there are a small number of failure modes that account for most repeated rejections. Here they are.
1. you’re solving problems silently
This one probably accounts for more rejections than any other single thing. In a coding interview, an interviewer can’t evaluate what they can’t see. If you work through a problem in your head and then type the answer, all they see is the answer , and if it’s wrong or incomplete, they have no idea how you think.
The fix is just talking. Describe what you’re observing about the problem. Say the constraints you’re thinking about. Mention the approach you’re considering before you commit to it. This is not natural for most people , it feels like narrating yourself doing a task, which is weird. You have to practice it specifically.
(A note: this is also true for system design questions. “I’m going to start with the data model because…” is more useful to an interviewer than staring at the whiteboard for 90 seconds.)
2. you’re not listening to hints
Interviewers give hints. Most candidates don’t register them as hints. When an interviewer says “what if we needed to handle this for a million users?” they are telling you that your current approach doesn’t scale. That’s a direction, not a casual question.
I think this happens because people in interviews are so focused on their current line of thinking that they treat anything from the interviewer as an interruption rather than a signal. The interviewer’s goal is for you to succeed , they’re not trying to throw you off. If they ask a clarifying question, there’s a reason.
3. your behavioral answers are too vague
Here’s an example of a vague behavioral answer:
“I had a conflict with a teammate, and I resolved it by communicating openly and finding common ground.”
That tells an interviewer exactly nothing. Who was the teammate? What was the actual disagreement? What specifically did you say? What happened afterward?
The STAR format (Situation, Task, Action, Result) is a useful skeleton, but the mistake is treating the skeleton as the answer. Real behavioral answers have names, dates, and uncomfortable specifics. “We had a two-week standoff over the API design in Q3 of 2024” is the beginning of a real story. “We had a conflict” is not.
According to research published by the Bureau of Labor Statistics, management and cross-functional collaboration is flagged as a core competency in almost every professional job listing. Interviewers asking behavioral questions are trying to get evidence for that competency. Vague answers give them no evidence.
4. you’re starting to code too fast
This one is counterintuitive. Starting fast feels like a good signal , confident, experienced, knows the problem. But most interviewers actually want you to spend 3 to 5 minutes clarifying the problem before writing any code.
Jumping straight to code suggests one of two things: either you’re not listening carefully (you pattern-matched on the surface features of the problem and started solving a different version of it), or you’re nervous and falling back on busyness. Neither is a good read.
Ask clarifying questions first. What are the input constraints? Are there edge cases we should handle? Is there a time or space complexity target? That 3-minute conversation usually prevents a 20-minute dead end.
5. you’re practicing wrong
Grinding LeetCode alone in silence is not good preparation for an interview. It’s good preparation for solving LeetCode problems. Those are not the same thing.
The interview is a performance under social pressure with another person watching and asking questions. The only way to practice that is to replicate those conditions. Record yourself talking through problems. Do mock interviews with a real person, or with something that responds and asks follow-up questions.
The Stack Overflow 2024 Developer Survey found that the majority of developers who prepared for interviews said practice with another person or a tool that simulated interaction was more useful than solo problem-solving. That’s not surprising , the skill you’re building is interactive, not solitary.
Tools like Craqly are specifically built to give you that interactive practice environment , the AI interviewer asks follow-up questions, notices when you go quiet, and gives feedback on your verbal explanation, not just whether the code compiles. It’s not a replacement for practicing with humans, but it’s a useful supplement for grinding the communication part specifically.
6. you panic when you’re stuck
Getting stuck in an interview doesn’t disqualify you. How you handle getting stuck often does.
The bad version: silence, followed by visibly spiraling, followed by a frantic attempt to try anything and see what compiles. This is readable to an interviewer in real time, and it’s uncomfortable for everyone.
The better version: say you’re stuck. Say what you’ve tried. Ask if it’s okay to think out loud for a minute. Break the problem into smaller pieces and say which piece you’re having trouble with. Most interviewers would rather see someone handle being stuck gracefully than see them power through a correct solution with no communication.
I’d also push back a little on the idea that the goal is to never get stuck. Some interviews are designed with problems that are intentionally harder than the interviewer expects you to fully solve. What they’re evaluating is your process when things aren’t going cleanly. If you only practice problems you can solve fluently, you haven’t practiced the most important part.
The harder truth
Some rejections are just noise. You interviewed on a bad day, the team had an internal candidate they wanted, the bar shifted because of a budget change nobody told you about. This happens more than candidates realize, and it doesn’t mean something is wrong with your interview technique.
But if you’re failing interviews consistently across multiple companies, something is fixable. The patterns above account for most of it. The fix for almost all of them is the same: get feedback on your actual performance, not the result. Record a mock interview. Have someone watch you solve a problem. You will notice things in 10 minutes of observation that months of solo practice won’t surface.
What do you think you’re getting stuck on?
