Interview preparation journey

expand-icon
Journey
I started preparing for the placement right after the first year. I had prior experience in coding with C++ as I learned it in 12th class. So, I started doing DSA directly after revisiting some key concepts of C++ and then I moved on to Machine Learning. I was having a keen interest in the field of AI so I decided to get into this field and I learned ML. By the end of 7th semester I was ready for attempting interviews at various companies.
Application story
I applied to this post on linkedin. I was texted about this openings by my friend who was already posted in Lowe's India, he also motivated me to apply to the openings. I applied on this post on the same post after which I got mail from HR which stated that you have to complete an assessment by 14th of Feb and if selected in this round, you will proceed further in the selection process.
Why selected/rejected for the role?
I think I was on point with my coding solutions to the questions asked in the interviews. I provided the optimal solutions and I was giving correct explanations to some theory questions asked. I was also able to design a nice and feasable system in the assessment task.
Preparation
Duration: 6 months
Topics: Data structures and algorithms, OOPS, operating Systems,SQL, DBMS, Machine Learning.
Tip
Tip

Tip 1 : Practice DSA questions, interview questions as much as you can.(400 leetcode questions) + (1000+ geeksforgeeks score) is good approximation of your preparation.
Tip 2 : You should have a good internship experience or 1 or 2 good projects on Android/web-d or Machine Learning.You should be through with your projects and be able to tell further improvements for the future.
Tip 3 : Be CONFIDENT with what you say. Don't murmur or speak in the mouth.The interviewer wants to know your thought process.

Tip 1 : Resume is the first impression of you.so it must be very eye-catching. write some decent (maybe 1 or 2 is enough) projects on resume.
Tip 2 : Should be through with each and every point you have written on your resume. people usually write 10- 15 skills on resume while confident in only 5.Please don't do it.

This was the technical round, held around at 10 AM IST on Google Meet.
Firstly she greeted me and asked me to tell something about myself, to which I introduced myself, explaining my academic and some projects also.
After that we moved on to the Hackathon project, which was smart cart self-checkout system. I explained the project along with the code, wherever necessary.
Every word you say while explaining should be clear to you.I used Firebase and SQL while explaining my project, to which she asked some questions related to it, 
Then she moved to the DBMS part, types of joins,what is indexing, how to approach if you were to design a payment system.
At last she asked me some Data Structure questions, which were of medium complexity
