Quick Tips and Strategies for Succeding in System Design Interview Round
Try to follow the 80-20 rule during your interview, where 80% of the time you will be speaking and explaining everything and 20% of the time your interviewer. Don’t use buzzwords and pretend to be an expert if you don’t know something.
- You read some blog posts or a few topics today and tomorrow is your interview, during your interview if you throw some buzzwords like “No-SQL”, “Mongo DB” and “Cassandra” then it may backfire on you.
- You can’t make a fool of the interviewer who is an industry expert, always consider that your interviewer may ask for more details and justification so if you are using technology X or database Y then “why?”, prepare yourself for this kind of question.
- Do not go into detail prematurely.
- Many times it happens when a candidate starts explaining one part of the system, they go into too much detail about the component and forget about the strict timeframe and other components.
- Maybe the interviewer wants you to stop somewhere where they don’t need too much detail. So to avoid this mistake wait for the interviewer’s feedback or response.
- They will give you some hints or will direct you to whatever part of the system they want you to explain further.
- Don’t have a set architecture in mind
- Like MVC or event-driven and try to fit the requirement somehow in that architecture. Maybe it’s not suitable as per the requirement. Requirements may change during the interview to test your flexibility so try to avoid this mistake.
- Be honest during your interviews
- If you have never used technology X then you don’t need to be fake in that situation. Try to find common solutions and show them your honesty, confidence, and willingness to learn something. That will make a good impression on the interviewer.
- Your practical experience, your knowledge, your understanding of modern software systems, and how you express yourself clearly during your interview matter a lot to designing a system successfully.
