Failing an interview due to a lack of qualifications is forgivable, but it is tragic when highly qualified candidates do not get an offer due to being unprepared. With the amount of information freely available today, the time and effort required to prepare for an interview is extremely low and a relatively small investment to make in your career.

Typically a candidate will have at least two or three days advance notice to do some research and prepare for any interview. Here is a checklist of things for technologists to investigate to be sure you are ready for what will come your way.

• Company intel – Learn as much as you can about the company, and try to have at least one minute of material memorized to answer the “What do you know about us?” question. Be prepared to present on the company history, the products or services the company provides, details on the business model, and the industry itself (competitors, health of the market, etc.). For technologists, the ability to give an eloquent response to the “Describe what the company does” question is a hugeasset that should not be overlooked and could be a significant factor in your success. Gathering substantial information on a young company’s funding status or finances might be difficult, but there will generally be at least some info in press releases from venture partners.
  
  

• Tech environment – Get specific details about the technical environment by doing some basic web research, reviewing any available job descriptions or LinkedIn employee profiles, and talking to your recruiter or any appropriate company contacts you may have. What frameworks, languages, databases, operating systems, and hardware are they using? Even if the details aren’t all entirely relevant to your interview, it will show that you are taking this process seriously. Look up any buzzwords or acronyms you don’t recognize so you can at least discover if you may have experience with a related item (“I haven’t worked with ______, but I’m familiar with ________ which appears to be a similar tool/language”).

• Tech moves – Knowing the company’s current tech details is valuable, but knowing about some of the company’s technical history will show great initiative while also providing potential insight into how the company views technology and makes tech decisions. Has the company made significant changes to their stack, and if so, why? Are they heavily invested in open source? Do they seem closely linked to a specific vendor? Does the company have an engineering blog or a company GitHub account for you to explore that might contain this information?
  
  

• Interviewer intel – Insight into the technical background and past employers of the individual(s) you will meet is a great advantage, as you may have some similar history. Personal GitHub or Twitter accounts? Technical blog posts? A LinkedIn or web search of the interviewer(s) might turn up some helpful details to use during the interview, as long as you use the info wisely. Showing that you did some research displays initiative, as long as you respect personal space.
  
  

• Confirm the basics – Where are you going and who should you ask for when you get there? Who are you meeting with and what is his/her/their role in the company? What is the preferred dress code? (NOTE: Some companies actually ask that candidates dress more casual, so be sure to ask)
  
  

• Prepare questions and anecdotes – Most interviews will provide you with at least a brief opportunity to ask questions. Although you ideally want to have these memorized, it is generally a good idea to have some questions listed so you don’t forget them under possible duress. There are also some fairly standard questions in the “tell me about a time when…” family which are commonly answered with anecdotes. Give some thought to past challenges, failures, and successes, and especially what lessons you learned from each project.
  
  

• Documents – Some companies may ask you to fill out an application and other relevant documents before the interview. Find out if this is the case and if so get those completed before interview day. Make sure to print out at least three copies of your resume and one copy of your list of questions. Think about who you will list as references if asked on the application, and have their info (name, email) available.
  
  

Keep in mind that making a solid impression in an interview is something that can make a huge impact down the road, whether or not you get the job. Interviewers remembercandidates who impressed, and they absolutely will remember those who crashed and burned as well. Do your homework and take interviews seriously, not just for the sake of getting this job but for opportunities later in your career.
