Help Desk and Technical Support positions require a balance of both technical and customer service skills. Whether supporting internal or external clients, being tech savvy and having strong interpersonal skills are a must.

Remember that every technical environment is different. Some Help Desk professionals take five calls a day but solve problems from start to finish. Others may receive 100 calls a day but the issue is referred elsewhere for resolution. Asking the right interview questions is the key to ensuring a candidate will thrive in your environment. Pick from the questions herein that make the most sense for you.
