海外博士后面试经历_高聚物单分子光谱 at University of St Andrews
|
|
我找海外博士后，投过126个简历，有过十几次欧美博士后面试。其中印象深刻的是英国大学的2次面试（下面就是其中之一），因为我不是被问教科书知识就是被问到答不出来；还有两次美国大学的华人老板面试，其中一个当场给了offer，结果后面email交流offer细节之下发现是坑，因为没有假期和自付保险；还有中美联合项目的面试，是给offer最早的(一般国内的offer肯定是最早到的)，却在内地大学的人事部这个环节上不顺畅，最后发现也是坑。这么多次面试、拒信和offer，我最后的选择是最符合我的能力和兴趣的，所以说这个被筛选和筛选offer的过程，正是对自己的科研能力和兴趣越来越明晰的过程，最终达到一个劳资双方都匹配的状态。回头来看，我是应该感谢那两所英国大学如此严格的面试以及拒信的，否则即便我拿到了他们的offer，我的表现可能很差，最终双输。当然，伴随着这个找博士后过程的是焦虑、恐慌、诱惑，人难以很从容地做决定。但是，我的经验是即使面试当场给了offer、面对当场答应就解脱的诱惑，自己都必须冷静几天考虑一下在平静状态下再做决定。也正因为此，我会将这些博士后面试经历陆续分享出来，希望对其他找海外博士后的虫友有所帮助。 skype interview for the postdoc position of single-molecule spectroscopy for polymer by 3 people (Dr Carlos Penedo, prof. Ifor Samuel and hr): 1. i present my research summary but is interrupted at 8 min, being suggested to talk about the snom. 2. prof. samuel asks how many time i spent on optical instrumentation, measurement and fabrication; i said that in phd most time spent on fabrication and measurement by renishaw invia, but in postdoc 50% on instrumentation and 50% on fabrication. 3. prof. samuel asks how i collect the tcspc signals; i said i splitted the signals and directed it to a picoquant detector. 4. prof. samuel asks how i use the tcspc for lifetime measurement; i said we made gan cavities of different q-factors exhibiting different photon lifetime. 5. prof. samuel asks something about the radiative- and nonradiative decay; i said, but later interrupted, the we combine the tcspc with the snom for illumination/collection mode and near-field illumination/far-field collection mode for the radiative decay lifetime measurement. 6. prof. samuel asks me the most important parts in contructuring confocal microscope; i said precise pinholes and laser-scanning head. 7. dr. carlos asks about the relation between objective aperture and resolution; i said large objective aperture can lead to better resolution as large aperture can collect more light for better signal-to-noise ratio. 8. dr. carlos ask which solution, water or oil, is used to improve resolution; i said oil because oil has higher refractive index. 9. dr. carlos ask what parameters can be changed to improve the resolution; i said the wavelength of illumination light and refractive index. 10. prof. samuel asks if i do nanosphere lithography myself and how to make si nanopillars to si nanotips; i said yes and annealing si nanopillar to silica and etched by hf. 11. prof. samuel asks how can i manipulate the molecule; i said that i can use dielectrophoresis and plasmonic optical trapping. 12. dr. carlos asked how i link the dna to the nanopillars; i said by using s-bond for synthesized dna and physical adsorption for natural dna. 13. hr asks if i have other interviews and job offers; i said i have. 14. hr asks when i will be availabe; i said april. 15. i asks what are my job content and role; prof. samuel said to build microscopy for single-molecule spectroscopy with magnetic tweezer. 16. i asks if i need to prepare the samples myself; prof. samuel said samples are provided by collaborators; 17. prof. samuel asks if i know why the project focus on conjugated polymers; i said they are for oled and some aggregated polymers will emit light but separated ones cannot; 18. i asks if i can bring family and the medical benefit;prof. samuel said yes and my family is covered by the medical insurance; 19. i asks when i know the result; prof. samuel said it would be next week. end. 24/02/2016. i was finally rejected. |
