How to prepare for (and ace) the technical interview

Rich Hein | Aug. 28, 2013
As developers and IT pros you need to do all the things everyone else does to prepare for a job interview such as update and focus your resume as well as work on your communication and presentation skills. However, you also have the technical interview to deal with.

Cashman adds, though: "Don't ever fudge it. If you're sure you don't know, don't pretend you do. Try and draw a parallel or make a connection between something relative that you have worked with." says Cashman.

You want to absolutely make sure you understand the question and then you want to finish up with a confirming question. Did that answer your question? Did I provide you with the answer you are looking for? Is there any part you'd like me to go into more detail on? "Don't assume, because many times there can be a disconnect, so ask them to confirm or clarify on the front end, answer the question and then confirm it on the backend," says Reed.

Have a Strong Closing
Many interviews end awkwardly or flat. Instead use this time to express your enthusiasm for the role and to let the interviewer know why you are the right person for the job. This is a great time to work in some of the points that you wanted to be sure you expressed to the hiring managers.

After the meeting, jot down any notes, thoughts or feedback you have while the memories are still fresh in your head. You should also write down the interviewers' names, roles and any other relevant information.

Follow-up and Send a Thank You Note
As with any interview, you want the interviewer to remember you for the right reasons and a thank you note with some additional details or thoughts will help do just that. Think about the interview and address any feedback you were given.

Prepare Yourself With These Sample Technical Questions
Cashman offers some actual questions and problems that employers use to qualify candidates. Each set of questions will be unique to the position and they will range from the core fundamentals to the higher principles, depending on the role at hand. However, these will give you some insight into what to expect. You can also look online to find some more of the common technical questions associated with your particular arena of knowledge.
