-**Q: For interviews, do I need to know everything here?**
+**Q: 面接のためには、ここにあるものすべてをやらないといけないのでしょうか？**
 
-**A: No, you don't need to know everything here to prepare for the interview**.
+**A: いえ、ここにあるすべてをやる必要はありません。**.
 
-What you are asked in an interview depends on variables such as:
+面接で何を聞かれるかは以下の条件によって変わってきます:
 
-* How much experience you have
-* What your technical background is
-* What positions you are interviewing for
-* Which companies you are interviewing with
-* Luck
+* どれだけの技術経験があるか
+* あなたの技術背景が何であるか
+* どのポジション職位のために面接を受けているか
+* どの企業に面接しているか
+* 運
 
-More experienced candidates are generally expected to know more about system design.  Architects or team leads might be expected to know more than individual contributors.  Top tech companies are likely to have one or more design interview rounds.
+より経験のある候補者は一般的にシステムデザインについてより深い知識を有していることを要求されるでしょう。システムアーキテクトやチームリーダーは各メンバーの持つような知識よりは深い見識を持っているべきでしょう。一流テック企業では複数回のデザインインタビュー面接を課されることが多いです。
 
-Start broad and go deeper in a few areas.  It helps to know a little about various key system design topics.  Adjust the following guide based on your timeline, experience, what positions you are interviewing for, and which companies you are interviewing with.
+まずは広く始めて、そこからいくつかの分野に絞って深めていくのがいいでしょう。少しずつでの様々なシステムデザインのトピックについて知っておくことはいいことです。以下の学習ガイドを自分の学習に当てられる時間、技術経験、どの職位、どの会社に応募しているかなどを加味して自分用に調整して使うといいでしょう。
 
-* **Short timeline** - Aim for **breadth** with system design topics.  Practice by solving **some** interview questions.
-* **Medium timeline** - Aim for **breadth** and **some depth** with system design topics.  Practice by solving **many** interview questions.
-* **Long timeline** - Aim for **breadth** and **more depth** with system design topics.  Practice by solving **most** interview questions.
+* **短期間** - Aim for **breadth** with system design topics.  Practice by solving **some** interview questions.
+* **中期間** - Aim for **breadth** and **some depth** with system design topics.  Practice by solving **many** interview questions.
+* **長期間** - Aim for **breadth** and **more depth** with system design topics.  Practice by solving **most** interview questions.
