CircleCI Blog

Since the beginning of 2018, we have had over a thousand candidates pass through the engineering hiring process. Our engineering interview consists of four stages following an initial screen. We broke down the percentages of candidates that pass through each stage of our hiring process, and it looks like this.

Out of any group of 1000 applicants:

250 will pass the initial screen.
117 will pass the hiring manager phone screen.
44 will pass the micro-skills assessment portion of the interview.
7 will pass the macro-skills assessment.
Fewer than 3 will pass the on-site interview and receive offers.

Following our Series C, we’ve ramped up our hiring further, building on what we’ve learned so far. We’ve been talking a lot internally lately about how we interview, and thought folks might be interested in what our interview process looks like for engineering roles, and why.

7 Things to Do Instead of Deploying

Around this time of year, many companies institute a “code freeze” that puts a stop to new deploys for a certain period of time (often to wait out the holiday retail rush, or until teams are back in full force in the office post-vacation).

While new features may not be going out to customers during this time, that doesn’t mean that meaningful work isn’t happening on engineering teams. This is a time that is full of planning, roadmapping, and setting teams up for success in the coming year. It can also be a fruitful time for personal or team-wide experimentation, goal-setting, and fine-tuning of existing systems (for example, migrating from CircleCI 1.0 to 2.0)

I started at CircleCI HQ in San Francisco as a Solutions Engineer this past August. With a job history of working at much larger companies such as eBay and PayPal, being at a start-up was a big change for me.

And so I found myself grappling with a new problem: how to onboard. I was more accustomed to super structured week-long (or even longer) onboarding formats, which I had found to be dry and data-heavy.

At CircleCI, the culture is very remote friendly. My manager Kevin lives in Seattle and works remotely from there. I have co-workers on my team based out of New York and Colorado. For my first week, Kevin traveled down to the San Francisco office to welcome me and to kick off the onboarding process. It was really helpful to have some 1:1 training time and to get some suggestions on what areas to continue focusing my time on. Solutions Engineers lead the technical implementation and day-to-day management of CircleCI Trials, ensuring early customer success and a long-term business relationship. New hires in this role often start with a week on support duty to help learn the product.

After the newness and excitement of my first week, I felt a little unsure of the best way to soak up more CircleCI tribal know-how. There were plenty of people who could answer any technical questions I might have, but during those beginning days and weeks I didn’t always know quite what (or whom) to ask.

We’ve recently been exploring signals around engineering productivity in order to share metrics teams can look at to know if they are on the right track (more on this to come). To be frank, we were surprised to see that Code For America was leading the pack in measures of engineering velocity. We spoke to two members of their team, John O’Duinn and Ben Sheldon, to learn more about how a non-profit focused on delivering services for the public sector is able to maintain incredible speed and engineering productivity.

Last year for Halloween, we put the call out for tales from the developer crypts that have kept haunting you, lo these many years.

We had so much fun we decided to do it again, and the timing proved eerie…

What follows is a letter to potential CircleCI employees, from our Head of Human Resources, David Mann.

Dear CircleCI Candidates,

I wanted to share our philosophy and standards around the hiring process to give you more clarity about what you should expect from us, and what we’ll look for from you.

Overall, know this: we respect you. And we’re honored you’re interested in joining our team.

To make the interview flow go smoothly, we have some standards we live by. We’re not perfect, but we do our best to make the getting-to-know-each-other process as enjoyable as possible. And as you consider joining our team, I want to share with you the thinking behind our methodology.

The Perks of Going Distributed

Since our early days, CircleCI has purposely embraced building a global workforce. This simple choice has given us many advantages. First, we have access to the best talent on Planet Earth. The great variety of viewpoints we have access to helps us make better decisions. Equally important: it allows us to continuously deliver value to our customers 24 hours a day. Having team members all over the world brings many advantages for us as a company.

What’s even more valuable, though, is knowing that the flexibility to work remotely confers some pretty great benefits on our global employees as well.

Hello CS

As a kid from Compton, CA who had never even heard of “coding,” if someone would have told me 4 years ago I would be majoring in Computer Science I would have given them my eyes of suspicion.

I am originally from Compton, California (yes, “Straight Outta” Compton, and no, I have not seen the movie) and I am currently pursuing my Bachelor’s degree at UC Berkeley. I went undeclared my Freshman year after realizing that my major at the time, Chemical Engineering, wasn’t (and wouldn’t) make me happy. Something was missing.

Gaining access into the world of tech hasn’t been the easiest thing for me. I grew up in East Baltimore; I know how unfair the system is. People talk a lot about diversity in tech. Seems to me they think of diversity as what can be seen on the surface, but I believe it’s much deeper than that. For example, most of the other African American people I know in tech came from homes that had both parents and went to really good schools; I grew up with a single mother and went to community college. I dropped out once I finished all my core CS classes so I could start working. People in the Valley get admired when they drop out of elite schools, but if you’re not dropping out of Stanford, you don’t get congratulated. It’s all dependent on your demographic situation.

A Step-by-Step Guide to Updating Legacy Processes in Your Org

Changing the way teams work is hard. Just think how hard it is to change just yourself. Then sprinkle in the difficulty of getting a group of people using various applications moving in the same direction.

We’ve talked to a lot of teams, and we’ve heard many variations on the same theme in terms of obstacles they foresee in implementing continuous integration:

“My company is a 20 year old company with established processes. Bringing in Continuous Integration would be a huge change to our culture, there are security implications, and it requires a major retooling. I’m going to have to sell this to my boss.”

So, where do you start when embarking on selling a new idea to your boss, to your team, and to everyone else you need to convince to invest?

After a bracing conversation with Alek Sharma, our developer advocate, I decided to write an equally bracing call-to-arms describing our hiring process.

So, you’re a software engineer. You’re adept at creating value from abstract concepts, weaving functions together in the loom of your mind. You know that Real Problems™ involve Real Work™ – a potent blend of success and failure, mixed thoroughly and served with a little umbrella.

ACT I
An open office. A circular dependency.
Evening.

Estragon, sitting on a low ball, is trying to reboot his computer. He pushes the power button with both hands, panting. He gives up, exhausted, rests, tries again. As before.

Enter Vladimir.

ESTRAGON:
(giving up again)
Nothing to be done.

VLADIMIR:
I’m beginning to come round to that opinion. All my life I’ve tried to debug it, saying Vladimir, be reasonable, you haven’t yet tried everything. And I resumed the struggle.

(He broods, musing on the struggle. Turning to Estragon.)

So there you are again.

Think back to your last one-on-one with your manager.

Did you go for a stroll about town? Did you get coffee? Do you get coffee every single time you have a one-on-one? I hope not, that’s a lot of coffee. It probably made you jittery, didn’t it? Made it hard for you to form words that make sense.

You had a perfect argument for a new tool or process, but it died young on your tongue because of the toxic levels of caffeine coursing through your veins. Yes, sometimes words can be hard. And soft, too. Actually, words come in a variety of textures, and that is the beauty of language.

Software engineers come into this world as blank slates–empty vessels to be filled with facts, yes, but mainly opinions. Opinions are the carbohydrates of programming: they have little nutritional value but occupy space, leaving you with a remarkable feeling of (false) satiety.

CircleCI has hired from many different talent pools, and is delighted to have smart and creative female, female-identified, and non-binary people on its staff. For this year’s International Women’s Day, I asked if any of them would like to share their thoughts about working in tech. And luckily, a few of them were willing to do so, as you can read below. (And p.s.: we’re hiring)

This year we wanted to express our love and appreciation for the devs + ops folks in our lives… in verse. Here are our favorites.

Happy Valentine’s Day, wherever you’re deploying.

A new survey released by Glassdoor showed that “DevOps Engineer” was one of the top “Best Jobs in America”, second only to “Data Scientist”. The annual ranking is based on salary, job openings, and an overall job satisfaction rating.

2016 was a big year for CircleCI. We had an $18 million Series B round, and released the closed beta of our 2.0 product. Along the way, we saw some great content. Here are the 5 blog posts that got the most views in 2016.

’Twas the night before Christmas, and all through the startup
were grim engineers who had taken old BART up
to put out a fire that users had found;
they hacked and they Slacked but did not make a sound.

80+ people. 7 countries. 16 cities. 37 pieces of luggage. We recently brought every member of the worldwide CircleCI team to our San Francisco headquarters for a full week.

Nearly all of our team

Despite the logistical briar patch that arranging a company-wide all-hands can be for a business of our size, the cultural, social, and company benefits of all of of us being in the same place at the same time is invaluable, and well worth a couple of bramble snags.

CircleCI Engineer Tad Whitaker knew he would teach kids about software principles when he volunteered to participate in an international program called Hour of Code. But as he helped students at San Francisco’s Argonne Elementary School for two days this week, he had a surprise: a rise in productivity and engagement when a technical problem forced the students to pair program.

Last year CircleCI Founder Paul Biggar joined forces with the Edith Harbaugh, CEO of LaunchDarkly, to create To Be Continuous, a show about continuous delivery and software development.

Killing Your Build Servers For Fun And Profit, But Mostly Profit

There’s an infamous quote that circulates among writers: “Kill your darlings.” How violent and succinct! And, as it turns out, quite applicable to software delivery.

Dev horror stories. We all have them. For Halloween, we’ve collected a handful of tales that still haunt our team and others on Twitter. We tried to keep them short, but like Python 3 adoption, they sometimes took longer than originally anticipated. Enjoy.

This is part of our ‘meet the team’ blog series where we get to know the faces behind CircleCI. In this post Jenneviere sits down to tell us a bit about herself, how she joined CircleCI, and what fuels her passion.

Andres joins the team at CircleCI as an Summer 2016 intern. Andres sat down with us to tell us a bit about himself, how he found himself at CircleCI, and where his adventures will take him next.

The fact is, people need to know what my position on things are. And I can't just say "please don't do that", because people won't listen. I say "On the internet, nobody can hear you being subtle", and I mean it. And I definitely am not willing to string people along, either. I've had that happen too - not telling people clearly enough that I don't like their approach, they go on to re-architect something, and get really upset when I am then not willing to take their work.
