Presenting a technical challenge is a standard a part of job interviews for software program engineer positions, which is used to check your skillset and expertise.
Right this moment I need to cowl some suggestions that helped me leverage my challenge’s presentation and can hopefully show you how to take advantage of out of yours.

The primary paragraph of your presentation must be very direct, simple to know, and make a transparent level. The interviewer ought to perceive what your challenge’s objective was, and possibly one necessary element (or achievement) you need them to take into account earlier than you dig into particular particulars.

To make this occur, the primary a part of your presentation ought to embrace the next parts:

  1. A “title” sentence that clearly summarizes your challenge.
    Begin with the underside line. For instance “I’ll current a 3-month challenge from my current office, during which I constructed the principle data-enrichment system of the corporate from scratch”
  2. An introduction to the corporate’s product, and/or the area of the workforce.

  • Guarantee your diagram incorporates sufficient info to ship related particulars, akin to the principle parts and applied sciences utilized in your challenge.
  • Think about together with just a few parts and applied sciences utilized by your workforce within the day-to-day work, even when they weren’t particularly used on this challenge. This enables for potential dialogue matters after you end presenting your challenge, showcasing further expertise and data.

Moreover, I want to organize two diagrams for the challenge’s presentation: one that gives a high-level overview of the corporate’s product or workforce’s area, and one other that delves into the challenge clarification itself.
Beginning with the high-level diagram reduces the possibility of overwhelming the interviewers, as they have already got the context and a common understanding of the system and product.

Listed below are my examples of structure diagrams:

Discover the colours — the elements of the system I labored on are marked in blue in each diagrams.
By together with extra parts within the diagram than I’ll truly focus on and highlighting the elements we’ll give attention to, I obtain just a few issues:
