About the Arrays (Merge Sorted Arrays) Test

When a role depends on strong algorithms and data structures skills, the Arrays section helps hiring teams see who can work with sorted data accurately and write efficient, reliable code. It is useful for identifying mid-level candidates with solid problem solving and the ability to explain their approach clearly.

  • Array logic and correctness: This area focuses on how well candidates work with ordered data and produce the correct result without dropping repeated values or misplacing numbers. The coding task shows whether they can apply practical array and sorting skills accurately across common edge cases and larger inputs.
  • Efficiency and code quality: Strong candidates do more than reach the right answer; they choose an approach that performs well as the amount of data grows. Recruiters can use this area to assess time and space complexity, along with code readability, structure, and maintainability in a real coding exercise.
  • Communication and scalable thinking: A follow-up video response asks candidates to explain how they would extend their solution for a broader use case. This reveals verbal communication, problem solving, and whether they can design an approach that remains useful as requirements change.

Frequently Asked Questions

At what stage of the hiring process should I share a skill assessment with candidates?

The ideal timing depends on the role, seniority, and region. Most companies send assessments before or right after the first recruiter call to focus on skilled candidates early. Our psychometricians and hiring consultants can advise on the best timing to ensure efficiency, fairness, and a great candidate experience.

Can I use my company’s existing assessments?

Yes, any organization can integrate its existing internal tests into the Canditech platform. Once implemented, your assessments can be automatically checked and scored, customized to match your branding, synced with your ATS, and easily reviewed by your hiring team. Our PhD-holding psychometrics team is also here to guide the entire migration process, ensuring a smooth and efficient transition.

Can I integrate Canditech with my ATS?

Yes, Canditech integrates seamlessly with 40+ leading ATS platforms, including Lever, SmartRecruiters, Greenhouse, Workable, Pinpoint, Ashby, Comeet, JazzHR, Jobvite, Teamtailor, HiBob, BambooHR, Recruitee, iCIMS, Workday, SAP SuccessFactors, and more. Our platform offers unique automation solutions that streamline your end-to-end hiring flow, allowing you to send assessments, track progress, and view results directly within your ATS. If you are looking to integrate, our team is here to help you explore the best options.

How does Canditech detect and prevent cheating during assessments?

Canditech helps maintain fair and secure assessments with advanced anti-cheating technology, including ChatGPT detection, copy-paste and tab tracking, device and location monitoring, webcam snapshots, time limits, randomized questions, and video-based questions to maintain integrity and accuracy. Learn more here.

Is Canditech an interview replacement?

No, Canditech doesn’t replace interviews, it makes them count by helping you identify candidates with proven skills early so you can focus your time on the people most likely to excel. The result is fewer interview hours, better conversations, and stronger hires. We believe technology is not a replacement for the personal touch!

From the Pro package onward, each company is assigned a dedicated account manager to guide onboarding and deliver ongoing support.

How does skill assessment software reduce hiring costs and demonstrate ROI?

Many companies using Canditech have reported measurable results, including a 50% decrease in time-to-hire, an 80% reduction in interview hours, and ROI improvements reaching 248%.

How does Canditech ensure a positive candidate experience?

Our assessments mirror real job tasks and incorporate your logo, colors, and video to create an engaging, branded experience. This builds strong face validity, helping candidates feel the process is relevant, job-focused, and designed to evaluate the skills that truly matter.
