Technical Interview

• Could you introduce yourself?

• Can you tell me about the most recent Next.js project you worked on? How did you improve its accessibility?

• Have you worked with TanStack Query? Do you prefer using it over fetching data manually? Why?

• If you had to choose between the Fetch API and Axios, which one would you pick, and why?

• What are Promises in JavaScript, and why do we use them?

• Imagine you have four console.log() statements: two synchronous logs one after another, one inside a Promise, and one inside setTimeout(…, 0). In what order would they be printed, and why?

• Where would you store an authentication token: Local Storage or Cookies? Why?

• How have you implemented JWT-based authentication in your previous projects? Can you walk me through the authentication flow?

• What’s the difference between throttling and debouncing? When would you use each one?

• If multiple API requests are sent one after another, how would you make sure an older request doesn’t overwrite the result of a newer one if it finishes later?

• What’s the most recent technical challenge you faced in your code, and how did you solve it?

• Suppose there’s a bug in production that you can’t reproduce locally. How would you investigate and fix it?

• How do you identify whether a React component is re-rendering too often, and how would you optimize it?

• Why might a useEffect end up in an infinite loop? What are the common causes?

سوالات فنی خیلی تیپیکال بودن و اگه چندبار مصاحبه های فرانت رو رفته باشید ویژه برای React/Next تقریبا تکراری ان. مصاحبه بی جهت خیلی طولانی بود اما فضای دوستانه‌ی خوبی داشت. با این‌که زیر مجموعه‌ی دات وان بودن، از نظر مالی خیلی منعطف نبودن و ۵۰ تومن براشون زیاد بود. دو مرحله مصاحبه فنی و یک مرحله HR داشت که خیلی جالب نبود چون مواردی و مطرح کرد تحت اسم همدلی که بیشتر معنیش آچار فرانسه بودن توی شرکت بود و حدودا طی ده روز آفر داد.
