Hey everyone, happy to answer any questions around Data Science/ML/AI and making a career within it

A brief about me, I work currently as a Sr. ML Engineer at an Indian unicorn startup 
I graduated 5+ years ago and have since worked as a Data Scientist / ML Engineer at an ecommerce company and social media company. My designations have changed based on the industry requirements and work too changed based on that.

Would love to take questions on what it means to be an ML Engineer, my early learnings from a career in data science, and thoughts on AI.

Look forward to all questions :)

AMA 🎙️: Hi, I am diffusedbandit, Senior ML Engineer at an Indian Unicorn

Data Scientist

I am an ML engineer working in a startup.

My current situation is horrible,I am constantly stressed about getting laid-off(My performance is good,I got promoted a month ago). I came to know that my company will probably lay people off this month,since they are unable to meet targets.

Now,I got rejected in four interviews.
There is a lot to learn and revise.
Stats and probability.
Machine learning algos.
Deep learning architectures(got rejected because I was unable to explain the architecture of a complex model in detail).
DSA(got rejected twice in this round).
SQL (got rejected once since I was unable to solve the SQL problem).
ML ops(some recruiters ask this as well).

With the added pressure of getting laid off,my whole life is turned upside down.I am unable to focus.
Every meeting or discussion I attend I feel like people are evaluating me.( This was not the case before).
I don't know what to do.
It would really help,if you guys share your interview experiences below.

Welcome to Software Engineers's Private Community

I am originally from a small town and did my BSc in Computer Science. My relatives and neighbours used to say that I am a good for nothing freeloader who is a "nikamma" - unemployed. It was very hard to find a job back then and I used to have deep anxiety about it. My only dream was to get my fathers appreciation. He is my biggest hero. 

So I started preparing very hard and practiced my skills. The only one who supported me was my mother who used to give me tea even at 3 in the morning while I used to study. Even my own father gave up on me and from time to time he used to say that if you are living under my roof then you have to follow my rules. He also used to say that look at the neighbour's ladka who got a government job and he asked me to prepare for Bank PO.

So I moved out from my town and shifted to Gurgaon where I got a small PG with some money that my mother had given me. I also started freelancing on Fiverr and which led me to improve my communication skills. Finally, when I got my Google offer letter I felt like I made it. It was the best response to all the taunts by people around me. 

I suddenly became a superstar in my town with people congratulating my parents. I bought my mother gold bangles and dad a new watch with my first salary. I was looking at my offer letter today and it reminded me of all the hardwork I did to achieve this moment.

This is the story of my life. In case anyone needs help. I am ready to provide support to aspirants here as a way to give back.

Family said I am good for nothing but I finally I got an offer from Google

This is what 100% of Indian men want to achieve since their childhood. Jewellery for Mom and Watch/Car for Dad. It is an appreciation for all the hard work they put in to help us succeed in life.

Software Engineer

I will be using a scale of 10 for better quantification. 


Python : 7/10
SQL: 7/10
PowerBI: 9/10
ML(Pandas): 6/10
PLSQL: 6/10
Advanced Excel: 8/10
Azure Databricks + DataFactory : Started learning
Apache Spark: Started learning
Communication skills: 9/10

Prior Work Ex: 1.8yrs as a PLSQL developer (started off as a fresher) + one SAP internship of 4months + one Data analyst internship of 1 month

Aspiration : Data Engineering Role

1. Is the above techstack enough to get me a good data engineering role? Will I be able to clear the technical rounds at companies like accenture, IBM etc with this profile? I have heard the barrier to entry for data engineering is higher than that of data analyst.

2. Do I need to learn DSA?

3. What salary range do I fall in with this profile? 


I seek your honest answer. I feel lost. 

Also, should I focus more on improving my cloud skills or shall I be more competent with my python skills? Which one would pay me off in a better sense financially? I certainly can not focus on all the tools at once.

Data Scientist role ready

Senior Associate

Hey guys, so I have been interning at a company for the past 9 months. They have offered me a ppo and I will most likely accept it. But my interest lies in the ML field or some data fields such as data engineering. 
Can anyone advice me how do I go about it?
Like should go for masters(my undergrad degree is not CS or some pheonix branch). Should I learn on my own and keep giving interview. Or should I take some experience in sde and then switch?
Thanks in advanced

Advice for switching from SDE to ML/Data fields

I am trying to switch to a Data engineering role in a product based company. Please suggest some great practices and strategies to learn DSA with python and SQL to crack interviews at product based companies. 
 I have experience working in AWS data orchestration where I worked on step function creation, Glue, lambda, event bridge. Also used version control like GitHub. 
 Please suggest a way to crack interviews at product based companies for data engineering roles.

Strategies for learning DSA with python, SQL, Spark

I have 6 YOE as QA. First 3 years I was into manual testing and now since past 3 years, I am an SDET with tech stack- python, pytest , playwright, selenium. I am planning for the job switch now. I have not used much of DSA in my work. However I understand DSA is a must to clear interviews. 

I need help in preparation. From where and How to start the preparation? 

Please update your strategies , so that it will be helpful for all those preparing for interviews.

Need help! DSA strategies!

So i have been working for 4 years now (data engineer and scientist)   and havent been enjoying much. Thinking of finally grinding and getting into better company.
PLEASE suggest resources for DSA grind which are currently trending and most optimised.
