J'ai passé un entretien chez DCA Design en oct. 2019
Entretien
Compled engineering questions emailed to me. I was then invited to an interview in Warwick, where I had a brief introductory chat with 2 people, which led into more engineering questions.
Questions d'entretien [1]
Question 1
Design as many mechanisms to convert horizontal motion to vertical motion in a 3:1 ratio as you can in the given timeframe.

The process involves some basic HR questions, elaborating upon your resume experience. They then ask you some technical calculations and mechanism design problems. They also provide you a basic device and ask you to explain how it works.

Design a mechanism that can convert horizontal linear motion to vertical linear motion
J'ai postulé via un recruteur. J'ai passé un entretien chez DCA Design (Warwick, West Midlands, England) en juill. 2023

Take home assessment before interview stage. 3 questions which were quite difficult.
Did not reach interview stage, withdrew my application. Not worth the hurdles they make you jump for such a low salary.

Question 1
1) If rain is falling vertically at 2m/s velocity, would a typical person get wetter if they walk slowly or faster between two points a fixed distance apart?
Would wearing a brimmed hat help and would its benefit be dependent on the walk speed?
2) Have to sketch a linkage for a torsion spring arrangement that will achieve a certain function. Diagram given.
3) A liquid dispenser needs to dispense liquid through a nozzle at a constant rate.
The liquid is held in a long flexible thin-walled polythene bag and is compressed by a spring-loaded platen with a force F.
Form an equation that expresses the force F that is needed to generate a pressure P in the bag when the platens are separated by a distance d.
To achieve the required constant dispense rate, the bag pressure P must remain constant. This means that the platen force F must increase as the bag empties. Sketch out a possible spring actuation system that would aim to achieve this.
