Top 5 Qlikview Developer Interview Questions
If you are planning to hire QlikView developers, you need to ask the right questions that will help you determine if the candidate is the right fit for the role. Here are some top interview questions for QlikView developers and insights into what hiring managers can learn from their answers.
In QlikView Management Console, what do you mean by tasks and triggers?
This question is essential to determine if the QlikView developer is familiar with the QlikView Management Console. A QlikView developer who has experience working with the console should be able to explain the difference between tasks and triggers. A task is a predefined script executed at a specific time or interval. Triggers, on the other hand, are actions that are initiated when a particular event occurs.
Tasks in QlikView Management Console refer to predefined scripts that can be executed at a specific time or interval. The console provides a variety of predefined tasks, including document reloads, backups, and distribution of QlikView documents. A QlikView developer should have experience working with these tasks and know how they can be scheduled and managed in the QlikView Management Console.
Triggers are actions that are initiated when a specific event occurs. A QlikView developer should be able to explain how triggers can be used to automate tasks or to create events when certain conditions are met. For example, a trigger could be set up to reload a QlikView document when a new data source is added or to send an email notification when a particular value is exceeded.
What is incremental load in QlikView Architect?
Incremental load is a crucial concept in QlikView that allows developers to load only the data that has changed since the last reload. This technique can help speed up the data loading process and improve performance. Hiring QlikView developers who are knowledgeable about this technique and can effectively use it in their development is essential.
A possible answer to this query is that incremental load is a data loading technique that only loads the data that has changed since the last load. This technique saves time and reduces the amount of data that needs to be loaded, making the data-loading process more efficient. It's essential to correctly set up an incremental load to ensure that only the required data is loaded.
Explain CAL (Client Access License) and write its types.
A QlikView developer should understand Client Access Licenses (CALs) since they are essential in determining the number of users who can access QlikView documents. This question is critical in determining if the QlikView developer is familiar with CALs and can explain their types, such as named user CALs, session CALs, usage CALs, and document CALs.
Client Access Licenses (CALs) refer to licenses that provide access to QlikView documents for users. CALs are essential in determining the number of users who can access QlikView documents, and there are four types of CALs: named user CALs, session CALs, usage CALs, and document CALs.
Named user CALs are assigned to users requiring frequent access to QlikView documents. Each user has a unique CAL and can access QlikView documents from any device. Session CALs are used when many users need occasional access to QlikView documents. Users log in to the system using session CALs, and the number of available CALs determines the number of users who can access QlikView documents simultaneously.
State the difference between information density and subset ratio in QlikView.
This question is vital for determining if the QlikView developer understands data analysis and visualization. Information density refers to the amount of information presented on a screen, while the subset ratio represents the proportion of data visible in a chart to the total data available. A QlikView developer who can explain the difference between the concepts can create visually appealing and easy-to-understand reports.
Information density is displayed on a chart, dashboard, or report. It refers to the number of objects, colors, and other visual elements representing data. While it is important to present relevant information, overloading a chart or dashboard with too much information can make it difficult for users to interpret the data.
Conversely, the subset ratio is the proportion of data visible in a chart or dashboard to the total data available. It represents the amount of data displayed compared to the total. A subset ratio can filter data and help users focus on the most critical information. QlikView developers need to balance information density and subset ratio to create informative, visually appealing reports that are easy to understand.
Define the trellis chart in QlikView.
This question is essential for determining if the QlikView developer is an expert in data visualization. A trellis chart is a grid of charts that represent subsets of data. This chart is commonly used in QlikView dashboards to display multiple charts compactly. A QlikView developer who can define and use the trellis chart can create informative dashboards that are easy to understand.
Additionally, a trellis chart can be customized in various ways, such as by changing the layout, format, and style to enhance its functionality and appearance. It allows the Qlik developer to display multiple visualizations side by side, making it easier for the users to compare and analyze data. With a deep understanding of the trellis chart in QlikView, a developer can create compelling data visualizations that enable users to make informed business decisions. Therefore, this is an essential interview question to ensure the QlikView developer can create compelling data visualizations using trellis charts.
