Should You Prepare for Technical Interviews? 6 Things to Consider
The tech industry is highly competitive and constantly evolving. This creates an imperative for candidates to be well-prepared for technical interviews. Let’s look at the potential effect of preparing for technical interviews and whether it’s worthwhile or whether you should just apply and wing it:
|
Practiced significantly (20+ interviews, 50 coding challenges) |
Some practice |
No practice, let's wing it |
|
|
How many applicants are you competing against, 8 or 800? |
Practice and not being terribly nervous will help set you apart from other candidates |
This depends on your appetite for risk… |
You better be a genius. |
|
How prepared will you be to tackle diverse and complex technical questions? |
You’ve got good chances, even if interview questions are a lottery. |
You’re playing a limited lottery and are really relying on your experience and existing skills. |
You’re basically playing the lottery. |
|
How ready are you to handle the psychological pressure of interviewing? |
Practicing the situation you’ll be in where “it counts more” will help you to reduce that pressure |
Depends on how you handle pressure… |
Great…for those who don’t feel pressure as much as others - a small % of the population |
|
How able are you to demonstrate your problem-solving skills? |
The more problems you’ve seen, the better off you’ll be. |
If you solve problems constantly in your current role, some practice and you should be fine. |
You’re betting on your existing problem-solving skills - which could be great or may need work… |
|
How good are you at answering questions such as “Tell me about a time when you…..” |
You’ll have already practiced answers and be able to communicate with confidence and whole sentences |
You may ramble a bit but overall provide a good-enough overview. |
Ummm and errrr while you hope some inspiration hits you, or you provide an ok but not great answer you regret later |
|
How up-to-date are you with industry trends? |
For those who like being prepared or having topics to talk about to show your passion, prepping is worthwhile (and useful anyways in this field). |
If you’re good at your job, likely some practice will be enough. |
If you’ve been in your job for 2+ years and haven’t explored what others are doing, you might be behind the curve already. |
Given the competitive nature of the tech industry and the multifaceted structure of technical interviews, what is adequate preparation and is worthwhile? Well, that’s up to you and it depends on where you want to fall in the items above. Bear in mind that preparing well not only increases the likelihood of performing well but also helps to showcase your full potential (even if you are the only viable candidate for a position!)
The Impact of Effective Interview Preparation on Success and Performance
When it comes to technical interviews, your preparation plays a crucial role in determining your success and performance. Instead of simply listing strategies, let's explore the importance of planning your preparation and its impact on your interview outcomes.
