5 Tips to Crack Low-Level System Design Interviews
Low-level design is very important when you have to design software-level components. It is one of the important components of software design and at the time of requirements you have to collect all the necessary points which are required to design the system. So, you can say low-level is a step by step refinement process.
The main goal of low-level design is to design the internal logical design for code. After that, it is easy to understand internal low-level design architecture. In this article, we are going to discuss the 5 main tips for low-level design which is helpful to crack the interview.
Key points:
- “No right or wrong” answer for the Design Question
- Understand and Read the Question properly
- List the requirements
- Think and be clear with your answer
- Practice Practice and Practice
**1. No Right or Wrong Answer For the Design Question **
In industries getting the better design of the product is an iterative process and a lot of times refactoring of code also gets to happen to improve it. However, in the interviews, we only have limited time to come up with the design which should good enough to convince the interviewer. Always start designing from the basic entity in your system and then iteratively proceed towards the higher components. That way chances of missing out the basic components are less in comparison to that if you start with big entities in starting.
2. Understand and Read the Question Properly
Often in the interviews, it happens that you get the question you have read earlier, don’t rush, and start to wring whatever you have just read, first understand the question completely, and then you must proceed. It may happen that the interviewer might expect some different requirements from what you read. Hence it is very important to be calm and listen to the interviewer patiently.
If you have read the answer prior to your interview it will definitely give you a head start, but don’t just sound like as if you have mugged-up the answer. Also, there are high possibilities that some of the requirements which you have read are different during the interview and in that case, if you just blindly copy-paste your already read answer, your interview will get a negative impression and the chances for you to crack the interview will fall drastically. It’s very important for you to understand the whole picture and then think before you jump to the conclusion.
**3. List the Requirements **
Don’t assume, just clarify with your interviewer about all the requirements and then write them down, this will help you to avoid the confusion later and it will also help you proceed step by step.
Once you have all the requirements clarified, they will become base for design and you will be able to proceed step by step accordingly. Without listing the requirements, you will be lost during the designing process as you will not have a clear reference for what to do next. It is very-very essential for the design that you have gathered all the requirements.
Once you have all the requirements clarified, they will become base for design and you will be able to proceed step by step accordingly. Start designing your system on the basis of listed requirements one by one.
**4. Think and Be Clear With Your Answer **
At the time of the interview, after getting all the requirements think and discuss with your interviewer. But many times it happens you are telling the wrong answer but if you have to think correctly then your interviewer can guide you. So, you can give the exact answer whatever interviewer expected and give you some hints, so discuss.
Remember the time in the interview is limited to 45 minutes to 1 hour and if you think that first, you will think come up with the whole design in one go and then explain the complete to your interviewer, believe me, it’s a blunder and that will not be successful especially in design interviews. Because there are chances where you can make mistakes during the process and if you will be continuously discussing it with your interviewer then he or she will definitely give you hints and tell you that you are going in the wrong direction, do so and so to correct it. Also, it will save your lot of time which you would be spending on correction and explanation later.
Always remember that your interviewer is there for hiring you and not for rejecting you, so feel free to seek help and hints if required, however, do not make it a habit at each and every step, seeking too many hints and help can also be negative sometimes, so you must be aware of each and every scenario.
**5. Practice Practice and Practice **
Just don’t underestimate the power of practice and being consistent, the only key to becoming better in anything is practice. So, before your interviews, you must have to read the notes which you have prepared or you can read the materials you have available to you. Sometimes it happens that whatever you have practiced the same question is being asked, in that case, you will always have an edge, but as we mentioned earlier do not just start writing the same blindly.
Take few questions and try to solve them and come up with the design on your own first and then if the solution is available somewhere just compare with that what is being missed or what can be done in a better way. Just do not go and directly read the solution, that way the learning curve will not be exponential. First, try and then go for a solution.
Often people make the mistake of just reading the solution and going for the interviews, believe me, that’s not a very good habit, always try yourself first and then watch out the available solution.

5 Top Web Design and Development Tips for an Awesome Web App
First impression is the last impression. This statement is absolutely correct when we talk about web design and development. In this blog, let us talk about the tips for a great web web app.
Web application development has come a long way since the beginning of the World Wide Web. The web environment today uses HTML and CSS to view data and content to users while JavaScript is used to interact with the client.
Did you know that when a visitor arrives on your website, you have about five seconds (or less) to capture their attention and keep them where they are? That’s not a whole lot of time to impress someone, so if your load time is not perfect or your site’s navigation is all over the place, you can say goodbye to your visitors.
Believe it or not, the rapidly changing world of technology is not helping with this, either. New trends can easily make your website outdated and render it all but useless, leaving you with fewer visitors than you started with.
So, now the below questions arise:
How are you supposed to fix this issue and keep your visitors?
How do you create a website that looks good, functions perfectly, and communicates your message clearly?
Developers and designers have various approaches to improve web design. Regardless of whether you have a perfect, smooth, and proficient site, that doesn’t mean it will suitable always.
You ought to consistently consider site improvement thoughts as time passes by.

BEING HONEST an essential UX interview tip
In this article, I share what I think is one of the best tips when it comes to design interviews.
As a junior UX designer, I’ve been asked a few times by my peers: what is the most essential UX interview tip I have?
Well, to this question I have a very simple answer,** just be honest**… well, this might sound like a no brainer, but it seems to me that not many junior designers know about it or want to apply it.
I had the chance to speak with a few designers and I discovered that some tend towards being a little bit insincere when going through interviews for design positions. It’s normal to be intimidated when going through an interview process and you might want to act as if you have more experience than you have to secure the job.
Well, I’m here to suggest that that’s not the right approach. I fact, recruiters know in advance that as a junior designer you won’t have many years worth of experience so instead of being insincere it’s better to show up with an open mindset and being honest.
A mindset of learning and improving is always welcomed and valued in today’s world. Simple answers like “I might not know X because I’ve haven’t had the chance to get at it but I can learn it as I’m an avid Lerner” go a long way with recruiters.
Put yourself on your recruiter’s shoes, would you rather employ someone “that answers to 90% of the requirements’’ but doesn’t show a growth mindset, or would you employ someone “that answers to 70% of the requirements’’ but shows it’s the thirst for learning and improving?
That’s not to say that you’ll show up with no qualifications at all. You still have to have a certain level of expertise. “Don’t be the guy with 30hrs of experience using Sketch and 1hr of prototyping experience calling himself a UX designer”.
Some skills can be rapidly learned with just a little bit of discipline and will so don’t be afraid to answer with a no if you haven’t had experience with certain techniques due to lack of opportunity of doing so, for example. It’s always easier to learn something new than being perceived as untrustworthy because you said you were qualified to do something but you finally weren’t.
keep in mind that being sincere is always the way… not just during job interviews but in life. Anytime you’re being insincere to achieve something, most probably, the lie will end catching you back and having the opposite effect you wanted it to have.
Anyway, I’ll stop with my “life lessons” and I’ll wish you a very successful interview.
Hopefully, this little advice does help you.

System Design Interview Tips
The system design interview provides the key signals that differentiate a tech lead from programmers. Here’s some tips may help you ace it.
Image from Quora
Pre-Interview Preparation
When preparing, thinking about how to design a system that top-tier tech companies have(Google, Twitter, Amazon, Uber, etc).
Proactively picking some classic questions, like Twitter Feeds, Snapchat messaging, Dropbox file system, to exercise. Over-preparing and ensure you are familiar with these major scenarios.
“Drive the discussion from the beginning.”
Explore The Restraints
After the interviewer throwing out the question, like “Design a Load Balancer for Twitter”.
Do NOT rush to the solution.
The very first thing you need to do is to get clarity about the system’s requirements and constraints:
- How many users we are talking about?
- How many tweets sent per sec?
- What are the latency requirements?
- How are we going to store the data?
- Clients are mobile or desktop?
- Clients are Push or Pull model?
- How many data centers we are talking about?
In reality, the quality of these exploring questions reflects the candidate’s experience level.
Complete Your Solution
Now that you have the clarity of the system’s requirements, continue to drive the discussion.
The next step is to write down the first version of a complete solution.
On a high level, a reasonable solution should include all the components that receive, process, and store the data. Specifically, we need to write down:
- Al the components’ key responsibility(E2E)
- Key data schemas
- Key algorithms of processing data, like load balancing algorithm
- How the system monitor and handle errors/exceptions
Then validate this solution with the interviewer, ensure the it satisfy the key business requirements. Sometimes it also involves a bit calculation to persuade the interviewer.
Optimize
After having the 1st version solution nailed, the interview will usually go into the “Deep Dive” section. The interviewer will come up with a special requirement, and ask the candidate to adjust their design to ensure its system survive in this scenario.
For instances:
- The QPS is very high
- Read is 10x than write
- Prioritize latency over accuracy
- Ensure data security
There’s no one-fits-all answer at this stage. The interviewer really needs to leverage his/her experience and resolve it.
However, there’s one thing each candidate should keep in mind.
“Think in trade-offs”.
No matter what solution you propose, always write down its pros and cons. What makes it work and what to sacrifice to meet this goal. That’s the key signal of an experienced engineer.
Ending
Unlike the coding interview, there’re hundreds of ways a system design interview could go. But no matter what scenarios you’re in, I wish tips mentioned above could help you navigate to the ideal destination.
