Data Engineering & Analytics

Placed at:

The experience with IK was phenomenal, it was totally worth it. After so many years I was interviewing and IK helped me a lot in orienting myself and to get into the rhythm. Had a transition from Goldman Sachs to Facebook. IK mentors guided me and told me not to worry about the preparation part and to focus on upskilling myself. That really made a huge difference.

Data Scientist II

Placed at:

Interview Kickstart has a very nice community. Everybody is very knowledgeable. Omkar is amazing. The way that he explains things is so great that it also taught me how to explain steps in problem solving well. Interview Kickstart's way of identifying patterns in a problem is the most effective part for me. Lastly, with the community, it enabled me to have a network of people that I can see different perspectives, and approaches to reaching solutions.

Software Development Engineer

Placed at:

IK offers high-quality study material, knowledgeable and patient instructors working at industry-leading companies, well-paced live classes + tests + review sessions, always available technical + career coaches, mock interview support from the best interviewers in the respective fields. IK brings together people with same the ambition (on their platform, UPLEVEL) to guide and inspire each other

Machine Learning Engineer

Placed at:

It has been a great learning experience. The structure is really good and the materials as well. The lectures and live class pre-reading material is very informative and engaging.

Software Engineer

Placed at:

I completed IK’s program and got offers from a couple of FAANG companies. Why you should take this course: It is well tested and the focus is more on the concepts/templates rather than approaching one problem at a time. You will meet peers who have similar aspirations. You can make groups and help yourselves.

Machine Learning Software Engineer

Placed at:

I liked the course that IK provided a lot. IK provided all the knowledge on a variety of topics that helped me prepare for coding interviews. The mock interviews were really great. Landing a job at my desired company has been a great pleasure.

Interview Questions

Career Path

Salary and Levels at FAANG

Frequently Asked Questions

The typical Data Science interview process at FAANG and other Tier-1 companies looks like:

- One coding round: Easy to medium Leetcode problems or Python-based Data Manipulation and Wrangling questions. SQL is often a part of these rounds.
**Behavioral round:**Open-ended questions to gauge if you're a "good fit” for the company.- 3-4 on-site rounds:
- One problem-solving/discussion round
- One take-home assignment round
- 1-2 domain rounds

1

One coding round

- Easy to medium Leet code problems or Python-based Data Manipulation and Wrangling questions. SQL is often a part of these rounds.
- The SQL round is pretty standard across all the FAANG+ companies. You’ll be asked to solve problems using common clauses such as JOINS, WHERE, and GROUP BY.
- Google tends to focus more on Statistical coding, some Data Analysis, and SQL since the company handles vast data sets.

2

One problem-solving/discussion round

- Inclined towards discussing your work experience, past projects, and problem-solving with a mix of statistics, coding, probability, and some quantitative aptitude questions.
- Facebook (Meta) focuses more on real-world data problems. So, prepare accordingly and provide concise answers when asked to elaborate on statistical terms.

3

One take-home assignment round

- Some companies give a dataset and inference-based questions to judge problem-approach/deduction skills as part of take-home assignments. The usual deadline is 24-48 hours.
- For the take-home assignment given by Apple, you’ll only be provided with three days. It will probably be a Machine Learning problem, and you’ll have to develop a model and give a prediction using the dataset.

4

1-2 domain rounds

- This round demands a deep dive into Data Science fundamentals. Interview questions in these rounds typically focus on designing experiments to meet certain business goals, A/B testing, and ML algorithms.
- You’ll need to be clear about how you frame the problem, the metrics you use, A/B testing, technical trade-offs, and so on, along with the required data analysis.

5

One behavioral round

- You can expect Data Science interview questions on your job experience and discussions on past projects along with open-ended questions to gauge if you're a "good fit.”
- When applying at Google, ensure that you have an answer for “Why Google?”. Such questions are asked at all FAANG+ companies.
- Thoroughly research each company's leadership principles and develop answers in the form of a story based on those characteristics.

Data Science Career Roadmap

A Data Scientist’s career path features two main career tracks:

- Individual Contributor roles
- Management roles

Data Scientist Career Path — Individual Contributor (IC) Roles

Individual contributors in the Data Scientist’s career path work on core data science tasks such as programming, creating models, coding, solving complex problems, and getting hands-on with the technical aspects of data science jobs.

Advanced or deep technical or hard skills are key to developing an IC Data Scientist career path.

Typically, the Data Scientist career path for an individual contributor (IC) follows this progression:

Data Scientist 1 → Data Scientist 2 → Senior Data Scientist → Staff Data Scientist → Sr. Staff Data Scientist → Principal Data Scientist

2

Data Scientist Career Path — Management Roles

A managerial role in a Data Scientist’s career path involves management tasks such as leadership, building relationships, conflict resolution, etc.

For software engineering managerial roles, a conceptual understanding of the technologies used is sufficient to perform managerial tasks. In contrast, Data Science Managers must have a working knowledge of the technologies used.

Communication, leadership, collaboration, and other soft skills are essential for developing a Data Scientist career path in a management role.

Typically, the Data Scientist career path in management follows this progression:

Data Scientist 1 → Data Scientist 2 → Senior Data Scientist → Data Science Manager → Sr. Data Science Manager

3

Qualifications Required to Become a Data Scientist

Depending on where you are in your Data Scientist career path, you will need the following educational degrees:

- Bachelor’s/Master’s degree in Computer Science, Software Engineering, or a related field; Bachelor’s degree for an entry-level position and a Master’s degree for higher-level Data Scientist positions
- Ph.D. in a relevant field is preferable and often a prerequisite for advanced or research and development positions.

You can also obtain professional certifications in the skills needed to pursue a career in Data Science. Some of the top Data Science certifications customized for Software Engineers and Software Developers to uplevel your Data Scientist career path are:

Tensorflow Developer Certification

Google Professional Data Engineer Certification

Amazon AWS Big Data Certification

Microsoft Certified Azure AI Fundamentals

SAS Certified AI & Machine Learning Professional

Facebook Data Scientist Salary

The different levels of Data Scientists at Facebook are:

IC3 (Associate Data Scientist): This is typically the level at which fresher Data Scientists or Software Engineers are hired.

IC4: Those hired at this level should have 3-5 years of industry experience. However, new grads can also be hired at this level, provided they can demonstrate skill and expertise.

IC5: Data Scientists hired at IC5 have at least 6-9 years of industry experience as they are required to lead complex projects on their own. Also considered the “terminal” level before a Data Scientist moves into the management domain as IC5 onwards, they perform more managerial responsibilities.

IC6: Most Data Scientists working at this level have almost 9+ years of experience.

IC7 and IC8: These levels require more than 10 years of experience.
