If you are an aspiring Abinitio professional, we have compiled a list of the most important interview questions that you can expect during your next interview.
Q1. Explain Abinitio and its architecture.
Whether you are a fresher or are an experienced professional, this is one of the first questions that is asked in every Abinitio interview. You need to be thorough while explaining the concept. Abinitio (meaning from the beginning) is a tech tool that is used to deal with the data.
Apart from this, it is also used for other purposes such as data manipulation, analysis, and graphical user interface based parallel processing.
The architecture of Abinitio comprises of:
- GDE (Graphical Development Environment).
- Enterprise meta-environment (EME).
- Conduct-IT.
Q2. What is the importance of data processing in the context of Abinitio?
As someone with prior experience in the field, you need to answer such questions smartly. The interviewer wants to see how thorough you are with the fundamentals of the data processing. Explain that since the data is generally collected from different sources, it may vary largely in a number of terms.
Such data needs to go through the various analyses and other processes before it is stored through data processing. It also saves a lot of time and helps in accomplishing various other tasks that matter.
Q3. What is your understanding of the overflow errors?
This is one of the frequently asked questions to Abinitio professionals. The interviewer is trying to assess your conceptual knowledge here. You need to explain that this is an error that occurs while processing bulky sets of data.
Such bulky calculations don’t always fit the memory allocated for them and in cases when a character of more than 8-bits are stored there, it leads to overflow errors.
Q4. Explain the function of dedup-component and replicate component in Abinitio?
As an experienced professional, you need to know all the fundamental concepts of Abinitio. Below are the functions of these two components:
- Dedup component is used to remove duplicate records.
- Replicate component combines the data records from the inputs into one flow followed by writing a copy of that flow to each of its output ports.
Q5. Explain the different kind of layouts that Abinitio supports.
By asking this question, the interviewer wants to check your previous work knowledge of Abinitio. You need to talk about the below layouts that Abinitio supports:
- Serial and parallel layouts.
- A multi-file system.
- A graph layout that supports both serial and parallel layouts at a time.
- A component in a graph system that can run 4-way parallel system.
Q6. Talk about the different types of parallelism used in Abinitio.
This is yet another common question asked at Abinitio interviews. The various types of parallelism used in Abinitio include data parallelism, component parallelism, and pipeline parallelism.
Q7. How can you run a graph infinitely in Abinitio? Explain.
Explain that to execute graph infinitely in Abinitio, the graph end script should call the .ksh file of the graph. Hence, if the graph name is xyz.mp, then it should call to abc.ksh in the end script of the graph to run it infinitely.
Q8. What do you mean by rollup component?
Here, you need to explain that roll-up component is a multiple stage function consisting of initialising 2 and Rollup 3. It enables the users to segregate and group the records on certain field values.
Q9. What is the meaning of dependency analysis in Abinitio?
Dependency analysis refers to the process through which the EME examines a project in its entirety. The process also traces how data is transferred and transformed in various stages from field-by-field, component-to-component, within and between graphs.
