Create Code Review Tests in minutes and evaluate engineersfor understanding language best practices and violations.
TRY FREEa. It's costly and time-consuming to conduct technical interviews with all candidates.
b. Home assignments significantly drop the application rate; high seniority candidates consider home assignments to be a waste of time.
a. Some engineers are shy, some are not, and some are hard to evaluate.
b. The algorithm challenges tell that the candidate knows algorithms and can code but say nothing about fundamental knowledge with a technology stack.
1. Only add functionality once it is necessary toavoid over-engineering.
2. Use custom exceptions for clarity and controlflow.
3. Loops should be optimized for performance,avoiding redundant calculations.
4. Clients should not be forced to depend oninterfaces they do not use.
5. Ensure they are descriptive, use CamelCase, andindicate the purpose.
6. Use exceptions for exceptional cases, notstandard flow control.
7. Use secure APIs and libraries for handlingsensitive operations.
8. Look for indications of code smells, like longmethods and large classes.
9. Handle session management securely withoutexposing sensitive information.
10. Document public methods and classes for clarity.
1. A TreeMapis used without a need for sorting.
2. A HashMapleads to performance issues due to poor hash functions.
3. Frequentautoboxing and unboxing impact performance.
4. Checkedexceptions are mishandled, causing code clutter.
5. BigDecimalis misused for financial calculations.
6. A HashSetis misused, assuming element order is maintained.
7. Aniterator is used where a for-each loop would be more concise and clear.
8. Autoboxingand unboxing negatively impact performance.
9. Floating-pointtypes are used for monetary values, leading to precision errors.
10. Concurrentcollections are used unnecessarily in a single-threaded environment.
Insteadof giving a coding challenge or moving candidates to the technical interviewstage, send them a Code Review Test and evaluate whether they qualify for thenext steps.
Your team has invitedcandidates to the technical interview. Sending a code review exercise beforethe technical interview allows an easy way to engage with the candidate.
You can provide a codereview test to the candidate during the technical interview and ask them towalk through their thinking process.
