2. Look at his previous work performance: look at his previous decoration design cases (text, renderings, manuscripts, etc. ), and asked him to introduce the ideas and ideas of the design cases he thought were better, and to examine his oral expression ability. At the same time, he can also find out whether the case was really designed by him or whether he only did part of the work.
3. Do a quick design test: give him a test question of decoration design and let him do a day's design on the company's construction site. The content can include the overall layout of the design, perspective renderings (which can be hand-painted or computerized), design descriptions, material descriptions, etc. Investigate his agile creative thinking, skillful procedures and technical skills of effect expression. Then ask him to introduce his own design scheme (this can be combined with interview and 2 points, and then choose another day after the exam).
Through the above investigation, we can basically find out whether the designer can meet your requirements.
