It could take anywhere from a few weeks to 4-5 months. 

For data engineering or data analyst roles, there aren't any good unified resources like LeetCode for software engineers, but there are several places where you can prepare. Websites like Kaggle and DataCamp offer resources that are helpful in data analysis and engineering skills. 

You should also focus on improving your knowledge of SQL and Python as these are commonly used in data roles. 

Additionally, understanding data warehousing concepts and big data technologies like Hadoop and Spark will be important if you want to work in a company at scale. PySpark is also a great consideration.

Plus where do you guys prepare from? Talking about data engineering or data analyst roles I know for software engineers it’s mostly leetcode but I don’t see any one place to study for data jobs 🙃

As a SWE having 5yoe in Java I find myself absolutely bored and done with this profile currently preparing to switch to Data Analytics domain and try to build my tech stack from there. I wanna ask how many of you successfully transitioned and what tips would you offer. Also query to managers who are interviewing such roles what are your expectations and suggestions. Any advice to help me is welcome

Career switch to Data Analytics

Software Developer

Hey 

I joined infosys in oct - 2022 and now it’s been 1.8 months. My tech stack is MEAN stack but I was on bench through the year, recently got into a project but for only 4 months. I developed and learned by my own and gained a better knowledge on angular.
Now the situation my company has made for me that I need to switch asap, within a month or two.

Can anyone suggest me how to prep specifically so that I get offers from other company.

My DSA skills are gone and feel like I need to learn again from basics.
I have knowledge about angular.

Can anyone suggest me how much DSA I should learn and focus right now to clear interviews.
I’m planning to get a grasp over python and start doing DSA questions in that plus polishing my angular skills too. 
I have basic knowledge of node.js MongoDb too.

Will I’ll be able to switch within this time frame?

Please can anyone guide me through it so that I can plan smartly and can switch.

Your help will be really appreciated.

Hi community,

I am starting to prepare to switch to another company. There are a lot of roadmaps to follow. I'm looking for an SDE role. Can you people put there Suggest what all topics to prepare for and some good platforms.

Preparation

An actual dumb thing I said was at my first Data Science interview at a top tech company here in Bangalore. Interviewer asked me about my projects, and me being unpolished, I said that I had done a regression project. So he asked me how did I measure whether the model was "good".

I said that, "The accuracy of the model was high"

Interviewer responded with, "...You know Regression tasks are measured with MAE/MSE/RMSE and not accuracy, right?"

Lmao. You live and you learn. 🤡

Most Uneducated/Dumbest Thing You Have Said In a Data Science Interview?

I am a data scientist with 4.5 years of experience and want to transition to software engineering. In DS, we do not code the ways its done in SW roles. Moreover, I am not from CS background. How do I get started on preparing to get into tier 1 companies as SWE / SDE if I want to achieve this in the next 1/1.5 years?
