I have been working in IT since 2010 and have been working on bigdata Projects  for more than 8 years.

My past work experiences are with Capgemini,Creditvidya,United Health Group,Prokarma, Apple.

Currently I am working as a Senior Data Engineer at Cloud Untitled Inc.

My profiles are active in linked in and

I keep getting requirements from various companies, recruiters that are looking for smart Data Engineers.

Since our course is full fledge and we cover every topic in detail, Our students finds it easy to crack most of the interviews.

All learners who are completing their course along with assignments,hackathon will be referred to various companies that comes to us.

However, we cannot help you placed just because you have taken course from us. You will have to study really well.

The placement assistance will be only for Indian Residence, As I have a great network here.

Feel free to see some of the success stories here.
First thing, 

We want you to start our free 45 hours of course that will help you to understand how we teach you step by step.
Once you build your foundation better. You will get confidence that yes, you can easy make your career in it.

To be an exceptional Data Engineer, You need to be good at Programming language.
As part of
DE1 you will learn Java 32 Hours.
DE2 you will learn Scala 60 Hours.

Also, we have a lot of problem statement to solve there by making you better in Programming Language.

We want you to join us, when you get confidence that OLC is the best platform for Data Engineering. 
With Intense practice and lot of training, I am sure you will be able to change your career ahead.

Bigdata is really a demanding technology and you can not  master it in just 30-40 Hours as promised by most of the training platforms.
Dont pay for just learning the fundamentals, which might not be sufficient to work in the Production level environment.

We have many students who have successfully changed their domain from non programming background to Big Data Developer.

Here are some of our success stories.
Yes. For every course you complete, You will be given a course completion certificate.

But Let me ask you one thing.
What are you going to do with that certificate?
Probably, Put them in the linkedin to show your achievement and get some CONGRATULATIONS?

Certificates can be helpful only to freshers who wants to showcase that they have done some training, Instead of sitting idle.

However when it comes to experienced professional, you need to show your work.
Nobody hires you if you say "I have 10 years of experience in BLA BLA BLA technology but I have learned Bigdata from OLC. Give me CHANCE"

We don't even recommend you to show your certificate and say I have 3 years of working experience in Bigdata and here is my certificate from OLC.
Why do you want to trouble your next Job?

All course completion certificates  that you get under premium brand by paying anywhere around INR 1,50,000 to 8,00,000  are useless at work.Unless it is not a FULL TIME Program.
Salary always depends on Few Factors

1. Company where you are interviewed and their pay standards.
2. Your total years of Experience
3. Your last drawn salary.
4. Your Interviewer rating and feedback
5. Your negotiation skills.

However, I always believe to balance the equation
Salary= 3*Y, where Y= total years of Experience.

With a good quality training, You can definately show case your talent in the interview and create a good impression of "Must Hire Candidate" rather than just getting feedback like "Ok Ok".

Many of our student with 5 Years of working experience have grabbed a salary from 15 LPA to 22 LPA.

Please check our success story here to know the salary they are offered.
I know you have  a lot of confusion after talking to so many people, training centers.

Here are some of the solid reason to join us.

1. Training is my part time job, Working in Industry is still my full time job. Hence you get to learn from someone who actually does it in production and this is really important.
    I am sure you dont want to learn from someone who just read the books. Would you?

2. We are offering you 45 Hours of Program absolutely FREE without asking you to pay.
    This is a symbol of our confidence.Try looking out for any other platform who can offer you 45 Hours of FREE program.
    I bet you will find none. This course is only for serious learner who has a desire to go beyond basics.

3. The whole course is 230+ Hours and goes for around 10 months.
    The course content is fully revised frequently and covers all the concepts asked in the interview.
    We have a real time interview question bank contributed by all big data interviewee who are not even our student.
    The objective was to create a great question bank. In return they get access to all the questions asked by other companies.
    We go through all these questions and make sure to add all that is applicable for our course.
    Link to the question bank is here
    So you will be prepared with the real questions only.

4.All the payment would be on EMI based. You dont have a fear to risk all your money.
    Anytime you didnot like our course(Thats not going to happen anytime), you are free to stop payment.

5. Great support after the course. We have a whatsapp group of 140+ members where we keep supporting everyone with any questions and doubt. 
    This helps everyone to grow.

6. Great Placement of our students.

    60+ Google reviews:(Started recently):

8. We conduct frequent hackathon for our Paid learners to help them excel at solving Data Engineering Problems.
    You can check the public hackathon here to understand the quality of the questions.
    If you know fundamentals of Data engineering, I will suggest you to try solving it out. Its not going to be easy.

Please feel free to compare this with any learning platform and I am sure you will still find us better in every aspect.
You can still learn Bigdata with Python instead of java.Several companies are working on pyspark and its related technologies.

However learning Java way would make your career more better.

Here is how?
Hadoop ecosystem component are built in Java, Hence easy integration. You can enhance the functionalities easily.

Ever thought why hadoop,spark,kafka,hive were not written in Python? If python looks simple and easy to you, wont it also be simple for framework developer.
Nothing beats the robustness of Java and yes that's the reason great products are still written in JVM based language.

Learning Java will be better for Data Engineer.
People come up with silly reason.
Java is old and python is new.
But do you know Python is  older than Java
Infact many associates who are working as data engineers take up my program to enhance their knowledge.

We all have to agree that at work, we are limited to certain portion of the technologies, whereas while looking out for a new job, The company expects a lot. 

Many associates comes to us for taking up the program to take their technical knowlege to next level.

As long as you are confident that you can easily manage your Hadoop knowledge, You can directly learn Spark and scala and take it forward.
The interview Questions are accessible only to the contributors.
All you need to do is upload your last 3 companies interviews that you attended in last 3 months and you will become the life time member of interview questions getting access to all the interview questions contributed so far.

Click here to know more about it.
Every training center has its own course and syllabus.

Just google Big Data course  and you will find many educational companies marketing "Become Big-data Developer in 30 hours with certifications".
If, it would have been so easy and short, then every body would have done it. Is not it?

In case you dont have programming background, You need to learn step by step.
It will take at least 8-10 months for working professional and 4-5 months for students to get enough knowledge to become a big-data developer.

At OLC, we understand your profile first and then recommend you the approach you should learn, so that you can become industry ready in minimum time frame.

Please dont waste your time in fancy courses. Time and money will never come back again.
