Applied online, contacted through email after ~2 weeks. First had to complete an online assessment which gauges your knowledge of C programming by having you debug a few snippets of codes. They said they would contact me within a day. They did not. Had to email them back in order to get the results of my assessment. Did not get in touch with anyone after 2 weeks so I just gave up and thought that I didn't do very well on my assessment even though I thought it was mostly straight forward and completed it confidently. Didn't seem like a very professional hiring etiquette to leave the applicant hanging after promising a follow up after the assessment.
