Every data engineering interview includes a SQL round. If you are: > Worried about job descriptions asking for advanced SQL, but you are not sure what advanced SQL means for an interview > Having anxiety about being unable to get a job > Frustrated with online SQL courses teaching the basic dialects, but not a step-by-step approach to problem solving If so, this post is for you. Imagine being able to dissect any SQL problem and make the interviewer say, I need this person on my team. That is ...| www.startdataengineering.com
Extracting data is one of the critical skills for data engineering. If you have wondered > How to get started for the first time extracting data from an API > What are some good resources to learn API data extraction? > If there are any recommendations, guides, videos, etc., for dealing with APIs in Python > Which Python library to use to extract data from an API > I don't know what I don't know. Am I missing any libraries? Then this post is for you. Imagine being able to mentally visualize h...| www.startdataengineering.com
System design interviews are usually vague and depend on you (as the interviewee) to guide the interviewer. If you are thinking: How do I prepare for data engineering system design interviews? I struggle to think of questions you would ask in a system design interview for data engineering; I don't have enough interview experience to know what companies ask. Is data engineering "system design" more than choosing between technologies like Spark and Airflow? This post is for you! Imagine being a...| www.startdataengineering.com
Do you use SQL or Python for data processing? Every data engineer will have their preference. Some will swear by Python, stating that it's a Turing-complete language. At the same time, the SQL camp will restate its performance, ease of understanding, etc. Not using the right tool for the job can lead to hard-to-maintain code and sleepless nights! Using the right tool for the job can help you progress the career ladder, but every advice online seems to be 'Just use Python' or 'Just use SQL.' U...| www.startdataengineering.com
Are you a data engineer(or new to data space) wondering why one may need to use Apache Airflow vs. just using cron? Does Apache Airflow feel like an over-optimized solution for a simple problem? Then this post is for you. Understanding the critical features necessary for a data pipelining system will ensure that your output is high quality! Imagine knowing exactly what a complex orchestration system brings to the table; you can make the right tradeoffs for your data architecture. This post wi...| www.startdataengineering.com
You know Python is essential for a data engineer. Does anyone know how much one should learn to become a data engineer? When you're in an interview with a hiring manager, how can you effectively demonstrate your Python proficiency? Imagine knowing exactly how to build resilient and stable data pipelines (using any language). Knowing the foundational ideas for data processing will ensure you can quickly adapt to the ever-changing tools landscape. In this post, we will review the concepts you n...| www.startdataengineering.com
