Ask HN: Interviewing, what did I do wrong?

From my years behind the hiring line...this is what probably happened:

While you did OK, you did not ace the 3-1 hour technical interviews, or they thought that you didn't make a strong enough impression in <insert important area for the job/company> - the follow up interview was probably intended to gauge those areas, and you failed to meet their standard.

Don't feel too bad about it, people flunk out of interviews all the time - even if they would be perfect for the job - most places now adopt quite a strict hiring policy because a bad hire is worse for the business than a no hire.

You could try and get feedback form the company but I wouldn't hold your breath. Simply try again with another.

You may not have done anything wrong. It's possible that you made a great impression and were a good fit for the job, but they had another candidate who had just a slight edge over you in some particular area. Don't let this discourage you.

I worked at Ticketmaster 6 years.

Only one thing matters: God. Without God, goes nowhere. With God, sure thing. Be afraid.

No matter how long it's been, interviewing is still a very subjective field. It is frustrating, no doubt, to not know what you did wrong but that's what subjectivity brings.

It might be the human resource people if big company. Human resource people wanted people with high achievement + specialty and cheap cost. My Advise,just find other company.. don't blame yourself for it.

Unfortunately humanity (including hiring managers) is extremely fickle so the reason could have been as simple as "You reminded one of them of someone who bullied them in high-school, so they lied and said you weren't qualified." IMO, about a good 30% of the time when something goes wrong it's literally as stupid as this. Don't blame yourself if you were nice, not arrogant, and qualified. Just blame random chance, because that's the truest reason that exists.

This is an important question. You did nothing wrong, they'd like to hire you, but there was just something about you that made them hesitate. And because they have a ton of candidates for very few jobs, that hesitation means moving on. But it's NO knock on you - it's just some tiny thing that they probably should have ignored, but because they're focused on making a decision, they'll use any excuse to eliminate you. Don't think another second about it.

It could be nothing to do with you. They are not looking at just you as a candidate, but several others at the same time. When interviewing, hiring managers look at a few factors including technical knowledge/competence, cultural fit and budget. You may fit all the requirements, but another candidate could have made a better overall impression.

It doesn't hurt to call the recruiter to get some feedback.

You said you "passed" the previous interviews before the last meeting. It is unlikely the interviewers share the "passed " assessment. We interview a lot and often run the candidates through multiple interviews and tests, before making a go no-go decision. Your decision is likely the cumulative of the multiple interviews. Don't feel bad about it, life's short, move on, There are plenty of companies hiring for software engineers.

I can't tell you what/if you did anything wrong. There's just too many factors, some of which a highly subjective ("cultural fit"). I did interviews for my company too and usually we would optimize our process highly to get no false positives, even if that meant we had a few false negatives. So again it's hard to say.

But what really bothers me is that you got a reply from a no-reply address. What the actual fuck. You were there for an on-site interview, this is not the situation where you send people automated no-reply-click-this-link mails.

If their HR doesn't have the time to send a short personal mail (or an automated one from a HR address that doesn't look like it's automated) that might be a red flag on how they treat their employees anyways.

You can try asking them, we at my company were usually happy to tell candidates that didn't pass, why they didn't pass. But we also didn't blow off people with a no-reply mail that were far enough into the process to have been onsite.

The only advice I can give you is to move on and do the next interview. Don't let this get to you.

you mentioned questions on scalability et al, answers to those questions are very subjective. I went through a similar experience at one of the biggest tech giants out there ... went something like this - i was in the final face to face interviews and did well in all of those IMHO. It was a big interview day at the company and lot of candidates flew in all over the globe. So all interviews done, we went for lunch in the cafeteria, and before I started I was called for another round of interviews (and couple of other guys were called too). To be honest I hate lunch interviews, I think its cruel! But anyways, I was asked about design and scalability etc. and that was the last interview that day. After a few days I get a rejection email from the HR folks. I was in the same boat as you are today ...

You're actually lucky that you even got a rejection. I have a friend who has interviewed at quite a few companies that are talked about in high regard by people in the tech industry and after his interview, he hasn't heard back at all.

I know him he is skilled and certainly worthy of serious consideration....so it has been surprising seeing how many have rejected him after an interview without a courtesy email.

You either weren't good enough or weren't a good fit. I've had situations where I interviewed at jobs where I'm asked "What type of work will make you love coming to work and also what is your ultimate career goal". If your answer isn't exactly what they are looking for, you might not be "as good of a fit as they want".

This is actually a good thing because they are saving you a lot of time by getting you to work on something you like, rather than something might not know you don't like.

With that said, I expect that the tech hiring process will be unrecognizable a few years from now.

It's a numbers game. You need to be pursuing 5-10 job leads at any one time. You can be the perfect fit for the job, but it doesn't matter. Companies will turn you down for reasons which they will never be able to admit to and you will have to learn to turn companies down for certain reasons (which also you probably shouldn't say publicly). Remember, offices range from laid back, low pay, and easy to work with to psychopathic coked up management trying to ethnically cleanse all the people not of their country of origin (and brag about it later). Also, the hardest thing to do, and the most mature, is to always consider it was your fault whether not the right skills or not enough practice. It may turn out not to be, but you have to consider it.

Not unlike the VCs who reject applicants, you may have been great, but others may have been more great.

Further, there might have been non-technical issues at play which are harder to understand/reason about, such as communication issues, confidence issues (both over and under confident), or issues with a perception about how much you cared about their particular product.

All of the latter elements are fuzzy and not worth thinking too deeply about, if you get rejected for those, then you are lucky you didn't end up working there, as it would not have been a good fit for either of you.

I have heard people come out of interviews with negatives as fickle as "they didn't make eye contact."

This doesn't mean that the person was rejected for that reason, but if you are adding up all the reasons not to hire someone, and the sentiment was decidedly negative, then it's going to mean the company will not make the investment in hiring that person.

Do not take this personally. Companies make mistakes in the interviewing process and reject great people all the time. I have seen some absolutely amazing programmers with the chops to work anywhere look for jobs. There is always at least one company that rejects them. It's their loss.

Do not assume that you did something wrong. The mistake could be on their part. You made it through all of those technical interviews, so you will be able to find work somewhere!

5 months ago, I did - no b.s. - 15 hours of interview process with a big tech company. I was so good in the interviews that I (very, very politely) was putting on a clinic for their devs. No word for a week, then I get an email from HR saying they are passing on me with no reason given...after 15 hours of process. A couple weeks later I did an interview with a company I wouldn't have considered because I was so discouraged...ending up liking the team a lot, got hired and 3 months in, it's the best job I've ever had so far.

Interviewing is completely different than in school.

When doing Math or Computer homework, you usually are given a clear reason why your grade was marked down.

When interviewing for a job, they will never tell you why they rejected you. For legal reasons, it is risky to tell you. They will always give something vague like "not qualified" or "bad cultural fit" or "other applicants were better", even if that isn't the real reason.

Also, it's normal to apply to a lot of jobs with a low acceptance rate. If employers interview 20 people for each position, (and they don't select better than random) then you'll get an offer for 5% of your interviews.

A no-reply@ email address? This seriously happened? You dodged a bullet.

If you reject candidates from a no-reply@ email address, there is nothing I or anybody else can ever do to help you in any way ever again. You are beyond help. You've found perhaps the one thing you could do worse than simply going dark on candidates you reject.

I wouldn't frame the question as "what did you do wrong". As other people in this thread have pointed out you may have dodged a bullet. It could very well be that this company is in the "wrong".

A better question to ask is what can you do to make yourself more attractive and increase the probability of closing the deal with the next company. Think like a salesman.

The fact that you told him you currently make close to what their interns make jumps out at me. Perhaps you think that would make you more attractive, but it may have had the opposite effect.

The head of engineering may have been told by his team that you have a lot of expertise, skill and potential and then all of a sudden he finds out you get paid at an intern level. He is going to ask himself what am I missing? If you are so good why doesn't anybody else value you at that level. People want to have a good feeling in their gut when they make a big purchase and a large previous salary gap may have unsettled that.

A better head of engineering wouldn't we swayed by previous salary, but the truth of the matter is a lot of decision makers are not perfectly rational.

My advice to you is to google strategies for dealing with the "what is your current salary" question and be better prepared for that situation.

Here's my best guess given what you wrote. The company felt that you were good enough to be an intern there. They also had other candidates that they thought would be better. They only take n interns a year. That started from the best candidates and worked there way down until they got n yeses.

Once you graduate this will be less of a problem. Most big companies are always hiring. If they like you they'll make an offer. This can still be a problem at smaller companies though. If they only have one or two positions to fill they'll usually tend to be pickier.

Companies should give feedback to candidates whom they deny positions.

1. What questions were answered incorrectly/mistakenly/insufficiently? 2. Code review on code quizzes, if they're expected.

Just checking but are you non-white or non-male or some other protected class?
