Smile gave me an in detail picture of industry practices and helped in planning for company-specific interview, tips to outshine in an interview.
Overall the session was very insightful.
I went through the entire guide and I must say its very well structured across 62 pages. Pretty easy going for any beginner.
The best part is that it covers a loooot of breadth which will immensely help beginners like me to get started with system design. Also, the example of polling widget you have used is unique.
Thank you so much for writing this!🤍
Hands down the simplest guide for system design to begin with!! Covers a lot of breadth and useful for interview preparations
Hi :) I am preparing for Senior Frontend Engineer interviews and I wanted to seek the help of a professional who can help me to navigate and clear the interviews. I reached out to Smile Gupta for the same and she loaded the session with a ton of value which I strongly believe will help me to ace my upcoming Senior Frontend Engineer interview. You might think you are doing everything right but trust me, there would be a lot of little things you might be doing wrong and seeking the help of an Engineering professional like Smile Gupta would definitely help you to identify these setbacks and as a result you could perform far better in your next interview round. Happy learning :)

I’ve been under Smile ma'am mentorship form past 1 month months, and it has made a huge difference in my learning. Having someone to answer to every few weeks has pushed me to stay accountable and work harder. The guidance has been invaluable, and I’m making much better progress than before. I highly recommend ma'am as a mentor to anyone looking for structured learning and motivation!
