How DevSkiller TypeScript coding questions work

DevSkiller TypeScript coding questions are powered by the RealLifeTesting methodology. This unique testing model allows you to analyze your applicants’ knowledge of TypeScript, their coding ability, and their problem-solving skills, all from within predefined test parameters.

The RealLifeTesting methodology is based on the idea that it is more effective to test a developer based on the work they will likely be doing for the role than with algorithmic tests. The system then recreates a realistic work environment in which to test candidates, resulting in a more accurate system for screening developers.

Key features

  • Analyze coding ability and not just academic ability
  • Save time and money with remote testing
  • The RealLifeTesting methodology offers a greater user experience where candidates can use their own IDE, clone to GIT, run unit tests, and access Stack Overflow/Github/Google for research.
  • Stringent anti-plagiarism tools implemented to ensure TypeScript test accuracy
  • Observe TypeScript coding questions in real-time
  • Automated results that non-technical recruiters can understand
  • Interview questions on typescript for experienced and less experienced developers

Skills tested in our TypeScript coding questions

  • JavaScript
  • ES5
  • ES6
  • ES7

What to look for in a TypeScript developer

TypeScript is a programming language developed by Microsoft that is a compiler for the JavaScript programming language. TypeScript actually originated from JavaScript specifically for the development of large scale applications. This means that many of the same attributes apply when hiring developers for either language.

TypeScript and JavaScript alike are easy to learn and very fast-moving, with new frameworks created frequently. Although it is helpful to be up to date with the latest changes, your TypeScript developer would be better to possess a deep understanding of the JavaScript language itself and the older libraries and frameworks. They can then use this knowledge to adapt to any changes. In addition, though it is helpful for any good TypeScript developer, to know at least one popular, tried and tested framework or library.

Like the look of our TypeScript coding questions but want more?

We find that some of our clients like the DevSkiller testing model, but they would like to get more out of our TypeScript coding questions. If you’re thinking the same, then no problem, we’ve got you covered.

With the DevSkiller online task wizard, you can build your own fully customizable tests. As long as you have someone technically-minded available to you, then it is easy to set which languages you want to assess, to allocate a time limit for each test or individual question, or to alter the difficulty level of each test.

To invest in the DevSkiller screening tool can be a big decision for you to make for your business. If you’re still unsure, check out what some of our satisfied customers have to say:

Victoria Cyczewska – Talent Acquisition Specialist at Stepstone Services

“We now have a tool which allows us to not only collaborate to create tests assessing technical skills we need to grow, but also to communicate internally and externally (with candidates). What is more, our technical recruitment process is now more structured. As an example, we use our technical screening results as a conversation starter during technical interviews.”

Magdalena Rogóż – Deputy Marketing Manager at Kodilla

“Using DevSkiller to grade tests is 2 times more cost-efficient while giving our students a much better test and preparing them for future recruitment tests.”

Julien Gauthiez – Talent Acquisition Manager EMEA at Criteo

“We use DevSkiller in 15 locations around our 3 regions (US/APAC/EMEA).

Frequently asked questions

What is RealLifeTesting?

RealLifeTesting is the cornerstone of DevSkiller TypeScript coding questions. It is a methodology that emulates the real-world scenarios that your applicants are likely to encounter through their work. The applicants are then set challenges based on what they encounter during the simulation.

This means that unlike other coding challenges or algorithmic puzzles, RealLifeTesting allows recruiters to accurately assess an applicant’s performance within the role before they’ve ever been given the job.

Successful candidates are those who can demonstrate a clear understanding and knowledge during their TypeScript test. Tests are evaluated automatically based on the ability to utilize resources like Stack Overflow and whether they possess the critical thinking to determine the quickest and most efficient solution to problems they encounter.

How are TypeScript coding questions evaluated?

As mentioned above, our TypeScript coding questions are evaluated automatically. One of the great time savers of DevSkiller testing is the DevSkiller platform gets to work automatically after each candidate completes a test. The results are compiled and reports are also generated automatically. The reports are clear and easy to understand for non-technical recruiters and assessment is based on coding quality, whether or not the solutions they came up with would run, and how they might work in edge cases. DevSkiller can also ensure verified test results with our range of anti-plagiarism tools.

How long does it take to set up DevSkiller?

A big advantage of DevSkiller testing is that it is remarkably easy to get started. Our IT experts have done the hard work for you. You can start sending out test invites to developer applicants, a matter of minutes after you’ve set up your account. Devskiller’s extensive library of predefined TypeScript coding challenges means you’re ready to hit the ground running.

Do I need to be a programmer to use DevSkiller?

At DevSkiller, we have designed our TypeScript tests to be as simple and as automated as possible. The idea is that non-technical users be able to verify the technical skills of the candidates being screened, regardless of the level being tested. Results are presented in an easy to understand manner as well. If you have a technical person on-site you can prepare a test from scratch, but you certainly don’t need to be an expert to use DevSkiller.
